Natural Rubber Reclaim
Natural rubber scrap has, for years, been the primary source for production of volumes of natural reclaim. Nowadays, raw materials such as de-vulcanized (recycled or reclaimed) old tyres are being extensively used in tyres, tubes, adhesives, automobile parts, conveyor belts, hose pipes, mats, battery boxes, rubber sheets, rubber flaps, et al.
At MV Enterprises, we use easily-procurable raw materials to produce natural rubber reclaim that caters to international standards, both in terms of quality and utility. Our brand ALSTRONG is trusted by leading buyers serving a host of industry verticals. Further, it’s our ability to produce high tensile tyre reclaim above 7.5 MPa that has enabled us to get an edge over our competitors.
Grades of Natural Rubber Reclaim
- ALNR-80 SF
- ALNR-65 F
- ALNR-50 SF
- ALNR-45 SF
- ALNR-40 F
Production Process
The feedstock of natural rubber reclaim primarily consists of truck tyre tread peelings. The raw materials are first freed from contaminants. The resultant material, in the form of crumb, is de-vulcanized through a combination of chemical, mechanical and thermal steps to obtain reclaimed rubber with a Mooney Viscosity in the range of 40-60. This reclaim can then be added to a vulcanization system for use as a masterbatch.
Advantage ALSTRONG
The key benefits derived from the use of ALSTRONG's reclaimed natural rubber concern the processing behavior of the compound. Lower power consumption and raw material costs make it a very feasible option for cost-effective production. The use of natural rubber reclaim ensures lower calendaring, mixing and extrusion temperatures and helps in increasing tack. The reversion and ageing performance of natural rubber (ozone, UV) improves the penetration of fabric and cord, thus increasing the service life of the end product. Further, the high-tensile reclaim rubber can also be utilized as a perfect substitute for natural rubber without compromising on the end quality of the products.
