Airfit
Airfit refers to the entire range of products made with aqueous dispersions of organic polymeric matrices, SBR (Styrene Butadiene Rubber) and polyisoprene. Once dry and vulcanized, they are transformed through mechanical processes into open cell structure foams, making these products highly breathable. The basic raw material (latex) is an aqueous emulsion of an organic polymer.
There are rubbers composed of a single monomer or basic element (such as Natural Latex (Isoprene) or Polyurethane latex (Urethane) and elastomers formed by the copolymerisation of different monomers (SBR latex (Styrene-Butadiene Rubber), NBR (Nitrile-Butadiene Rubber)).
Airfit technology enables a wide range of formulations through the incorporation of multiple, additives which enables the desired properties to be met, according to the requirements of each application.

Airfit Physical Structure
The Airfit manufacturing process uses special devices for mechanically foaming the aqueous polymer emulsion, surfactants, additives and air. The subsequent drying and vulcanization process enables a very open physical structure to be obtained for the material. This structure maintains elastic properties while providing high breathability. Its open cell structure facilitates biodegradation.
Airfit Chemical Structure
The main raw materials used in Airfit are SBR latex (styrene-butadiene copolymer aqueous emulsion) and Natural Latex (Polyisoprene).
Natural Latex 
This is obtained in a sustainable manner from the resin of the rubber trees (Hevea Brasilienses) grown in the tropical areas of Southeast Asia (Thailand, Malaysia, Indonesia, India), South America (Brazil, Guatemala) and Africa (Nigeria, Ivory Coast, and Cameroon) Natural Latex and Synthetic Latex, although they basically have the same chemical structure (polyisoprene), they differ in terms of origin, form and harvest season, treatment before and after they reach the factory.
Synthetic Latex 
There are various types, which are all similar to one another, with SBR being the most widely used. SBR latex is a synthetic elastomer obtained through the copolymerisation of a mixture of styrene and butadiene with the latter being responsible for the elastic part. Firmness is obtained from the interaction of the styrene groups with one another.
No Toxic / Noxious Substances
Contains no harmful products, heavy metals or restricted substances. Non-regulated raw materials are not used in production.
Renewable Sources of Raw Materials
Natural latex is a raw material that comes from a renewable resource.
Biodegradability
Its open cell structure provides it with a high degree of biodegradability, far superior to that of plastics and EVA.
Carbon Footprint
The production process consumes a low amount of energy.
Its durability allows an increase in the useful life of the product to reduce energy by performance.
Production residues
Possibility of recycling Airfit foam waste by various methods. Either by means of new reactions (if a series of technical conditions are followed) or by grinding and reincorporating the recycled materials into new foams.
Post-consumer waste
Possibility of recycling the product after its useful life by crushing and reincorporating the recycled materials into new foams.
If recycling is not posible, Airfit waste can be icinerated under controlled conditions.
