 GL3018 PBT resin Secondary Coating Materials Used for Optical Fiber
Product description PBT is very important secondary coating materials for Optical Fiber, It has excellent performance in mechanical /thermal /hydrolytic / chemical resistance properties and easy to be mechanical processed.
Properties  Advantages  Description
Mechanical properties High stability Small shrinkage scale, small volume changingin using, good stability in forming.
High mechanical strength Good modulus, good extension performance,high tensile strength, the lateral pressure of loosetube is higher than requirement of standard .
Thermal properties High distortion temperature Whether in the case of high load or low load ,the performance of distortion is excellent
Hydrolytic properties Anti-hydrolysis High performance of anti-hydrolysis make opticalcable more longer life than requirement of standard.
Chemical properties Chemical resistance PBT can tolerate most of polarity chemical reagent atroom temperature. And PBT is not compatible withfilling gel. at high temperatures and susceptible to erosion.
Processing technology  The recommended processing temperature:

Package: Two package ways, : 1. It is packed 900/1000KG per bag with the inner lining of aluminum foil material, outer lining of PE woven material. 2. It is packed 25KG per bag with inner lining of aluminum foil material , outer lining of kraft paper material. Storage and transport Transportation: It should not be exposed to get wet or humidity during transportation, and keep it dry, clean, complete and pollution-free. Storage: It is stored in a clean, cool, dry and ventilated warehouse away from the source of fire. If the product is found to be damped in rainy reason or with high moisture in the air, It can be used one hour later after it is dried at the temperature of 120℃ . GL3018 properties
