Product use
I produced the model 61008 dedicated fiber optic cable PBT is polymerized by PTA and BDO.,Through the solid phase modified into cable for PBT. This material is suitable for the production of all beam tube optical cable.
This material has the advantages of easy molding.ointment has good compatibility, good mechanical properties and electrical properties, hydrolysis resistance. It is widely used in cable industry.
Our company's PBT is suitable for all beam tube production ( φ1.5~12mm) , Has good processing properties and mechanical properties.
