GREEN RUBBER

Is a Russian company which is specialized in recycling innovative technologies for the rubber industry.

Currently GREEN RUBBER company

is ready to offer to his customers the following product with the application properties which you will not find in any other solution proposed for the rubber industry market now.

Butyl rubber compound GRB-11

Butyl rubber compounds produced by GREEN RUBBER company, are used as an additive in rubber compounds instead of butyl rubber (up to 60%) for the manufacturing of different industrial rubber goods. Besides our butyl rubber compound can be used by itself (independently) to produce rubber compounds which are used for the manufacturing of corrosion resistant coatings, sealing and waterproof coatings, mastics and some rubber parts. Our butyl rubber compound is also well-suited for the production of thin-walled parts and parts with smooth glossy surface.

Butyl rubber compound GRB-11:
  • Homogenous structure
  • No impurities
  • Odorless (cold product)
  • Absolutely smooth surface

Butyl compound is shipped in form of plates (5 kgs/plate). Butyl compound plates are packed in carton boxes of 25 kgs. Carton boxes are put on wooden pallets (up to 40 carton boxes on each pallet). The final weight of a wooden pallet with the product is up to 1000 kgs. Besides we can propose to you alternative packages if it is required.

ADVANTAGES

Optimization of production process

Hight quality materials

Minimal effects on the environmental

Good price

Introducing up to 50% of butyl compound into rubber compound has almost no effect on the consumer properties of the final product. At the same time, it is possible to increase the content of butyl compound up to 80% and even 100% but with a certain compromise of such properties as Tensile strength and Elongation at break. But herewith such features of butyl rubber as heat-resistance, ozone resistance, gas impermeability and others remain the same, almost as original. So the economic benefit is significant. The same graphs as above are also obtained if GRB-11 is added in EPDM rubber compound which is usually used to produce molded rubber strips, gaskets and other parts where high weather resistance is required.
