Solution Overview
Problem
Flame retardant polymer compositions containing copolyester elastomers face a challenge in maintaining mechanical properties, particularly tensile strength and abrasion resistance, when high loads of flame retardants are required for flame retardancy, especially in electrical cable applications.
Innovation Solution
A flame retardant composition comprising a copolyester elastomer with hard and soft polyester segments, combined with 0-30 parts of further polymers, 1-15 parts of a halogen-containing flame retardant, and 0-15 parts of a halogen-free flame retardant, achieving a balance between flame retardancy and mechanical properties.

1Object-affected harmful factors
If high loads of flame retardants are used to achieve flame retardancy, then flame retardant properties are improved, but mechanical properties (tensile strength and abrasion resistance) deteriorate
Solution Approach 1:
The patent applies parameter changes by optimizing the specific composition and ratio of flame retardant additives (halogen-containing and halogen-free) to achieve the desired flame retardancy while minimizing the negative impact on mechanical properties. This involves adjusting concentrations and types of additives to find the optimal balance point.
Solution Approach 2:
The patent uses composite materials by combining multiple flame retardant additives (halogen-containing and halogen-free) with the copolyester elastomer base material. This composite approach allows the system to achieve flame retardancy through synergistic effects while maintaining mechanical integrity better than single-additive systems.
