Thermoplastic rubbers STREL are produced on the basis of zayed Rubber blends with thermoplastic materials such as EVA, PE, PP, PU, PA. Special compatibilisation techniques and reactive extrusion methods are used to execute efficient cross-linking of elastic and thermoplastic phases in STREL.
zayed Rubber powder particles has modified/activated surface, and it allows to create improved binding system with thermoplastic matrix, and to improve processing characteristics and material properties such as elongation and tensile strength.
It opens up opportunities for the applications that were unreachable so far due to property deficiency for common composite materials based on ground tyre rubber.
STREL combines both high elasticity of vulcanized rubbers and the easy processing of thermoplastic materials. STREL properties are very close to thermoplastic vulcanizates (TPV), which are among the fastest growing market demand in the polymer industry.
The basic advantage of STREL over common thermoset elastomers is the ability to be remelted and reused. STREL materials can be easily recycled and can be used repeatedly up to 5-8 times without remarkable property losses. Another advantages are as the shorter processing times and the need for little or no compounding in the creation of materials/articles.
STREL material properties are quite comparable with the best thermoplastic vulcanizates (TPV) and thermoplastic rubber (TPR) materials currently available in the world market.
Different grades of STREL are available, particularly including xxxxx ones.
STREL combines favorable properties of elastomers and thermoplastics, and it allows them to have the broad …range, including in particular:
Building: roofing and flooring, expansion/seismic joints, sanitary ware ;
Construction: drainage seals, tube packing, seals and profiles, setting blocks;
Automotive industry: cast wheels, covers, seals, boots, gaskets, mats;
Electrical and electronics: hoses, insulators, cable covers;
Bitumen modification, particularly in asphalt compositions;
Consumer appliances: sporting grips, stock cushions, soft touch, closures, containers.
STREL is produced on the basis (more than 2/3) of surface modified zayed Rubber, which is actually secondary product. By this reason STREL has the unique combinations of the valuable properties and low production costs in comparison with similar analogous materials. It secures successful promotion and wide market application of STREL
