PB Polybutene

Polybutene (PB) is a thermoplastic (hot-meltable) polymerized from butene. It is non-toxic, odorless, and has excellent cold and heat resistance. It is called "gold in plastics".

PB tubes are often milky white.

After being made into pipes, PB pipes have very good compression resistance, but poor impact resistance and are prone to cracks. PB is more viscous after hot melting, and the cooling and hardening time is longer, and the construction difficulty is relatively high. When used as a heating system pipe, due to its good thermal insulation performance, it is not suitable for floor heating pipes compared to PE material with better heat dissipation performance.
