Poly-Urethane Rods, Sheets & Machined Components

POLY-URETHANE RODS, SHEETS & MACHINED COMPONENTS


Polyurethane Rod

Petrorays brings to you Cast Polyurethanes rods, Sheets, pipes & rollers which are very cost effective and dependable Elastomers. Cast polyurethane combines the performance advantages of engineering plastics, metals &ceramics along with the flexibility & resilience of rubber. We are manufacturers, suppliers, and exporters of polyurethane sheet in Mumbai, India to all over the world. Cast polyurethane is very popular for their high impact strength, load bearing capacity, high resilience, high abrasion resistance, and excellent resistance to oil and grease.

The applications of polyurethanes - where the actions of bearing, sliding, forming, stripping, damping, cushioning, resting or rolling are involved.

For better results &optimum performance and longer life, selection of appropriate grades of Cast polyurethane is important. Polyurethane rod can be formulated with permutation & combination of selective chemicals & additives.
