      Product Description
      Polybutylene Alloy

      Polybutene alloy is a new material developed in light of the weakness of polybutene-1 (slow crystal transformation and long molding time). It is synthesized with the in-reactor alloy technology, which improves the crystal transformation speed and the impact resistance of polybutene. We end foreign companies’ monopolies and supply high-quality raw materials to domestic or foreign high-performance pipe manufacturers.

      Product Advantages
      Gold in Plastics

      Polybutene alloy has excellent properties such as thermal resistance, pressure-bearing capacity, and creep resistance. The product made of polybutylene alloy has a long service life and can be used at high temperatures for a long time without damage or deformation.
