For Crumb Rubber

We use new technology with higher quality standards

We are dedicated to innovation that results in higher-quality outcomes for our clients. Our manufacturing facilities are custom designed and built specifically for crumb rubber production, with advanced equipment and technology that ensures all of your crumb rubber specifications are met.

We have invested in the most advanced tire recycling equipment to manufacture crumb rubber granules and micronized rubber powder. We have a capacity of over 100 tonnes of micronized rubber powder. Our crumb rubber plant is designed to produce the highest quality rubber powder at the lowest possible cost. Throughout our manufacturing process, we analyse particle size on a continuous basis. We conduct routine particle size, ash content, sieving graphs, metal, and other impurity testing on a regular basis.

Fact and sustainability report

Sun-Flex supports higher-value tire recycling to prevent tires from being dumped in landfills or illegally dumped in lakes, abandoned lots, highways, or sensitive habitats. Over 90% of scrap tires are recycled now via rubberized asphalt, synthetic turf applications, rubber moulded products, and other high-value manufacturing processes.

Recycling conserves significant amounts of energy, which contributes to the reduction of greenhouse gas emissions. For example, using recycled rubber in moulded products has a significantly lower carbon footprint than using other resins.

Crumb Rubber Granules

Crumb rubber is recycled rubber produced from automotive and truck scrap tires. During the recycling process, steel and tire cord (fluff) are removed, leaving tire rubber with a granular consistency. Continued processing with a granulator. It reduces the size of the particles further. The particles are sized and classified.

Crumb rubber can be used in many applications, adding characteristics that improve the properties of finished products as well as reducing costs by replacing more expensive virgin compounds.

We produce custom sizes ranging from 10 mesh to 40 mesh.

Infill Crumb Rubber Granules

The tire crumbs were poured in between the artificial grass blades, providing more cushion and support to the artificial fields. This was a better solution because it satisfied athletes while also helping to prevent major injuries.

Over the years, our company has completed numerous landmark projects for the supply of infill crumb rubber granules. Our crumb rubber granules have been tested for rohs and migration of certain elements in accordance with international standards.

Sun-Flex infill crumb rubber granules meet particle size, shape, bulk density, thermogravimetric analysis (TGA), U.V Test/Weathering 5000 hours, Toxicology DIN 18035-7, Toxicology EN 71-3 standards from Labosport Group.

Benefits for using Infill rubber granules

Resilient materials to hold turf up.

Shock Attenuation stabilize the turf carpet 3 different rubber granules size.

Good elasticity.

Provide safe cushions good resistance to weathering and outdoor aging.

100% virgin material, Excellent UV resistance.

Long lasting performance, Colour stability.

Micronized Rubber Powder

Sunflex Recycling Pvt Ltd micronized rubber powder (MRP) is a low-cost, high-performance, and environmentally friendly raw material that can be used to replace oil and rubber-based materials. We grind TDF chips to produce the highest quality micronized rubber powder. Sunflex Recycling Pvt Ltd converts used tires and other post-industrial rubber into micron-scale powders that are sold to manufacturers of advanced products such as high-performance tires, industrial rubber, consumer and industrial plastics, asphalt, coatings, and construction materials.

MRP is used as a compound extender to offset the use of natural rubber and synthetic polymers, as well as a process aid in the manufacturing of materials. Because it replaces commodity-priced rubber- and oil-based feedstocks, MRP can reduce formulation costs in some cases. According to some estimates, MRP offers up to a 50% cost savings over virgin raw materials.

Tire, automotive, construction, industrial components, and consumer products are among the industries that use MRP in their products. We have the capacity to produce more than 100 tonnes of MRP per month.

We manufacture three mesh sizes: 20 mesh, 30 mesh, and 40 mesh. Crumb Rubber has made significant investments in researching the best techniques, expertise, and products to make rubber powder a cost-effective part of your process.

Activated Rubber Crumb

Sun-Flex Rubber is about to start producing activated crumb rubber for future rubber technology. We’ve done a lot of testing with our own chemical and mixing technology. Tensile strength, elongation at break, and hardness shore *A were all successful.

This is a novel approach to rubber recycling. This helps to reduce the overall cost of rubber compounding. Activated crumb rubber is a novel, cutting-edge technology with a patented manufacturing process. In an automated process at room temperature, activated crumb rubber is a chemical modifier for the surface of rubber powder.

The sulphur links that connect the rubber chains in vulcanised rubber are broken down by this innovative and patented process. This allows waste rubber to be re-used while retaining the majority of the original rubber’s properties and characteristics. The newly developed patent will be used to replace the old method of producing devulcanized reclaim rubber. We intend to establish a dedicated manufacturing facility for the activated rubber crumb process.
