Poliform uses Class EPF-S E 0.5, wood-based panels, the most reliable in conforming to EU standards EN 120 and EN 717-2 and in line with the limits established by the American regulation CARB Phase 2, with respect to formaldehyde release. With respect to varnish, Poliform exclusively uses polyurethane coatings free of heavy metals and volatile organic compounds (VOC) belonging to the various classes within table A1 of the Italian Ministerial Decree of 12 july 1990 and/or Classes i and ii within table D of the Italian Ministerial Decree of 12 july 1990.

Using cold-press technology, polyurethane foam can be moulded into any shape. The viscoelastic properties (memory) of polyurethane foam ensure the immutability of shapes formed through cold-press process. Using the right amount of additives, the firmness can be adjusted for all comfort requirements. Moulding can also include support elements for seating, producing a self-supporting assembly. 

A durable and flexible polymer material with an open cellular matrix. According to current understanding, flexible polyurethane foam is toxicologically inert. Polyurethane is a combustible solid and should not be exposed to open flame. The polyurethanes used in the sofa core have varying densities: higher density foam is used in those areas that are weight bearing. 

A natural textile fibre derived from the fleece of sheep and camelids. Owing to its specific structure and to the dense crimping of its fibres, wool possesses hydroscopic properties (absorbs humidity up to 30% of its weight), and is highly insulating, elastic, durable and flame retardant. The fabric, commonly known as woollen cloth, is spun from carded wool and is always fulled and able to be napped.

Fibra vegetale ricavata dalla bambagia che avvolge i semi delle piante del genere gossypium. La fibra di cotone non presenta conduttività elettrostatica, non infeltrisce, ha un’altissima igroscopicità, non irrita la pelle, è anallergica e si può stirare ad alte temperature. Dopo il lino e la lana, il cotone è la fibra tessile più antica. La lunghezza della fibra ne determina la qualità: più è lunga, più il cotone è lucente, resistente e pregiato.

Plant fibre derived from the liber (the inner bark) of the flax plant (linum usitatissimum) and composed of nearly 70% cellulose. It is lightweight fibre that is soft and durable. Owing to its molecular structure, it can absorb water to up to 20% of its weight without the body feeling any wetness. These properties make it ideal for textiles that are in contact with the skin. Specifically, this anti-allergenic, breathable and anti-static textile makes it ideal for bed linens.

A plant fibre derived from the boll of the plant, which holds the seed of the species gossypium. Cotton fibre has no electrical conductivity, does not mat, is highly hydroscopic, does not irritate the skin, is anti-allergenic and may be ironed at high temperature. After linen and wool, cotton is one of the world’s oldest textile fibres. The length of the fibre determines the quality: the longer the fibre, the more lustrous, resistant and valuable it is. 

A plant fibre derived from the stalk of cannabis sativa similar to linen in feel, it is the natural fibre that is most resistant to humidity.

A plant fibre derived from the bark of the genus corchorus. It is highly hydroscopic and the fibre is coarse and strong. The threads that are derived from the plant are coarse, stiff and very strong.

Velvet is a fabric whose cut threads are very evenly distributed, with a short dense pile giving it its distinctive feel. Velvet is woven on a special loom that weaves two pieces of velvet at the same time. The two pieces are then cut apart and the two lengths of fabric are wound on separate take-up rolls. Velvet can be made from many different kinds of fibres but silk and cotton are preferred.

A natural animal protein fibre derived from the cocoons of the mulberry silkworm (bombyx mori). Under the microscope, silk fibre is uniform, very similar to synthetic fibres. One of the specific properties of silk is the length of the filament: this can reach lengths of up to 700-800 meters. This makes it the longest fibre derived from an animal. There are four categories of silk textiles: taffeta, twill, satin and jacquard. Silk is the most splendid, softest and finest of natural fibres–cool in summer and warm in winter.

A textile can contain two or more types of fibres: for example, cotton and wool, wool and acrylic fibres, etc. These blended fabrics have varying characteristics depending on the fibres used and their proportions. Generally speaking, the blending of fibres allows the textile to retain the main properties of the fibres that comprise it. For example, a blend of cotton and synthetic fibres increases resistance to wrinkling. 

These artificial fibres are derived by processing cellulose from various naturally occurring plants (the same plants that produce plant fibres), transforming and dissolving it using solvents and then forcing it through spinnerets to form a continuous thread or a floccule. This family of fibres includes: modal®, acetate, cupro, lyocell and viscose. Synthetic chemical fibers derive from synthetic organic substances that are polymerized to obtain long molecular chains (macromolecules), which can be spun in the form of continuous thread or floccule (discontinuous fiber). This family of fibres includes: acrylic, modacrylic, polyamide, polyester, polypropylene and polyurethane.

Regenerated fibre, obtained from wood chips and cotton spinning waste. It is extruded to form a continuous thread or floccule (also known as rayon). It has properties very similar to silk and, like most plant fibres, it is comfortable, durable (if kept dry) and is highly absorbent. It is used in blends with other natural or synthetic fibres.

A synthetic fibre that derives from a macromolecule composed of at least 50% acrylonitrile and is generally available in floccules. It is highly flame retardant and feels much like acrylic fibre to the touch. Moreover, it is resilient, shape retentive, fade and wash resistant, has a soft hand, is durable and dyes easily to bright shades, is chemical-resistant, easy to care for, insulating and non-toxic.

A synthentic fibre derived from a linear macromolecule that is a long-chain synthetic polyamide in which at least 85% of the linkages are attached directly to two aliphatic groups or rings. It can be used as a continuous thread or in floccules. The fibres are exceptionally strong, shape-retaining (excellent elasticity) and abrasion-resistant. It is easy to care for (washes, dries, does not require ironing), can be easily coloured or dyed and is wrinkle-resistant.

(Polyethylene Terephthalate), a synthetic fibre derived from macromolecules composed of polyesters and is available in floccules or as smooth or volumised thread. Trevira® is one of the trade names under which it is sold. It is long-wearing, easy to care for and resists fading, humidity and microorganisms. 

Hide is a protein material derived from the skins of cattle. Processing is referred to as tanning and consists of eliminating the outermost layer of skin and connective tissue (hypodermis). The most important layer is the dermis, consisting of fibrous fascicles of connective and elastic tissue. The upper portion of the dermis, called the grain, is considered to be the highest grade of leather, called “full grain”. 

Tecnocover is a general purpose material, made up of scrap leather, polyurethane and cotton. Scraps from the processing of natural leather are finely chopped and mixed with rubber, latex and other synthetic aggregates. Sheets of tecnocover can undergo various finishing processes, in order to render them as similar as possible to the corresponding natural version. One specifically important process is embossing, whereby the surface is impressed with a specific pattern that imitates the grain of natural leather.

Leather is a protein fabric derived from cattle and submitted to a tanning process. It is thinner and lighter than hide. General considerations. We give you some information that will help you to understand the characteristics of the leather and hides listed below. The leather derives from the epidermis of the animals that is constituted by various layers and originally has a thickness of around 1 cm. Quality. When speaking of full grain leather, we consider the most superficial layer of the epidermis that maintains the natural characteristics of the grain, veneer and softness (more or less scarred). The dimension of the grain does not determine the quality of the leather, but it derives from aesthetical choices. In the case of more economic hides, the inner layers are used and are manufactured to reproduce the natural characteristics of the leather (grinding and pressure moulding of the grain). Origin. The European origin of the leathers is without doubt to prefer to exotic or overseas origins (which present more defectiveness due to scars and insect bites because of the breeding in the wild). Mineral tanning. The tanning, procedure that wants to preserve the leather from the natural organic decadence, is also used to exalt the softness, the colour, and the brightness of it. It is generally realized with chromium salts; only in the case of high quality leathers a vegetable tanning is realized in order to get the most natural effect. Dyeing.

The dye that permits to get all the different colours starting from the natural one is done by immersion of the leathers in dye drums: we always use aniline, through dyeing the whole thickness (to be preferred to the superficial dyeing). Drying. The drying, generally made on frames in ovens, is done naturally at air for the finest leathers. Grain. The natural grain (not embossed) and the absence of grindings (a sort of smoothing) show the use of full-grain leather of a quality that does not need correction and retouch operations.Refinishing. The best final refinishing that then determines the aspect of the leather is the one finished with aniline, with a more natural aspect but also more delicate. The refinishing with polyurethane resins, instead guarantees great uniformity and resistance in the use. Thickness and dimension. A greater thickness determines a better leather and a greater dimension are to be preferred, as you have less waste in use.
