Polyurethane for shoe soles systems, ester based, generally bicomponents. EXTER is the trade name for polyol, URECOM for isocyanic part: URECOM + EXTER = UREXTER
The main use is the production of the footwear soles, but they are used also to produce technical articles such as Tires for trolleys or bicycle and wheelchair wheels, parts for the automotive industry, shock absorbers, gaskets, etc..
In comparison to other materials, especially all in the production of shoes soles, the Polyurethane advantages are:
- High versatility, high productivity
- Excellent resistance to abrasion and to wearing
- Excellent mechanical characteristics such as the load bearing, elongation, ultimate tensile strength, tear strength excellent cold mechanical properties, in particular the resistance at breaking under flexural stresses
- Good resistance to hydrolysis, good resistance to bacterial attack, climates or in the presence of perspiration, good
- Biodegradability of the manufactured article, excellent reproduction of the mold designers, good adhesion
- With other materials, good surface for painting.
Complete Range of ester base systems for footwear and technical articles can develop following customer requirement and needs.
In particular it has: Indoor soles systems -slippers: characterized by their lightness and load bearing, medium performance systems, such as soles for women’s and men’s summer shoes: articles in which density, load bearing, mechanical characteristics and flexural strength, from ambient temperature up to medium low temperatures, High performance systems for closed winter shoes for men, characterized by excellent flexural strength, even at very low temperatures and/or high resistance to hydrolysis, keeping at the same time good load bearing and acceptable density.
Bidensity safety soles systems, having very good balance of the characteristics previously mentioned and having also good resistance to oils, solvents and hydrocarbons.
Moreover this material can be produced with antistatic characteristics for avoiding the accumulation of electrostatic charges.
Mono – bidensity Soles systems for sport activities, in particular they have excellent grip, resistance to wear, are lightweight with excellent elasticity.
Packaging of UREXTER: 60, 230 kg metal drums.
Polyurethane for shoes soles systems are specially ordered by customer demand.
