The two components rubber Poly 75-75 is a very stiff polyurethane rubber that cures at room temperature (RTV). The Poly 75-75 has a Shore A 75 that is just a bit stiffer than a car tire. The very hard rubber is extremely good with applications as used in the concrete industry. The Poly 75-75 is widely used for making large molds and bulkheads for the prefab concrete. The Poly 75-75 and Poly 75-90 are also widely used in the production of hard rubber parts. The Poly 74 and 75 series rubbers can be used as casting rubber, brush rubber or spray rubber.
There are many additions of additives such as CAB-O-SIL, thinners, accelerators, UV stabilizers and color pigments. In addition to the Poly series products, the PT Flex products are available for the manufacture of rubber parts and any rubber products that may be processed.
