Co-developed with Qingdao University of Science and Technology , polybutylene alloy (PB-A) effectively improves the speed of crystalline transformation of polybutylene and impact resistance. As a high-quality raw material for green pipes and fittings, it is abrasion-resistant, high-temperature resistant, environmentally friendly, corrosion-resistant, anti-scaling, anti-freeze, and known as the "plastic gold".
1. Polybutylene alloy has excellent heat resistance, pressure resistance, and creep resistance. Products made from polybutylene alloy have a long service life and are deformation-proof. It can be used for a long time at high temperatures;
2. With a crystallization cycle of only 48 hours, it breaks the monopolization of foreign technology and improves the downstream inventory turnover rate.
