Introduction
Secondary coating material for optical fiber is an essential part of the composition of optical cable: It is mainly used for loose tube or tight tube layer in optical cable products:
It plays a protective role in the optical fiber in the optical cable: Its product performance plays an important role in the performance of the optical cable product: Therefore, a suitable secondary quilt is used:
It is particularly important that cladding materials are suitable for different application scenarios: At present, the secondary coating materials widely used in China include polybutylene terephthalate:
Alcohol ester, modified polypropylene, modified polycarbonate, thermoplastic polyester elastomer: Since the properties of each product material are different, they are used in different
in the same optical fiber and cable products:
GB/T 20186 "Secondary Coating Materials for Optical Fibers" is intended to consist of 4 parts:
---Part 1: Polybutylene terephthalate: The purpose is to specify the requirements and test methods for polybutylene terephthalate products:
laws, inspection rules, marking, packaging, transportation and storage, etc:
---Part 2: Modified polypropylene: The purpose is to stipulate the requirements, test methods, inspection rules, markings, packaging of modified polypropylene products:
Loading, transportation and storage, etc:
---Part 3: Modified polycarbonate: The purpose is to specify the requirements, test methods, inspection rules, and standards for modified polycarbonate products:
Logging, packaging, transportation and storage, etc:
---Part 4: Thermoplastic polyester elastomers: The purpose is to specify the requirements, test methods, inspections for thermoplastic polyester elastomer products
Rules, signs, packaging, transportation and storage, etc:
Secondary coating materials for optical fibers
Part 3: Modified polycarbonate
