Due to its chlorine resistance it is commonly found in swimwear. Being non-polar, polybutenes stick well to other non-polar compounds and do not mix well with water, making them water repellent. [further explanation needed], Because the chemical reaction of the water with the pipe occurs inside the pipe, it is often difficult to assess the extent of deterioration. Gum base main component of gutta-percha. Privacy Policy - The two ingredients are lovely when paired, but they arent interchangeable. Polybutylene is manufactured utilising Zeigler-Natta type catalysts which produce a highly isotactic thermoplastic. PBT resists solvents, shrinks very little during forming, is mechanically strong, is heat-resistant up to 150 C (or 200 C with glass-fibre reinforcement), and can be treated with flame retardants to make it noncombustible.
