What is the difference between TPR flexible duct and TPE flexible duct material
一. The difference between TPE and TPR
TPE,thermoplastic-elastomer. The Chinese name is thermoplastic elastomer, which is the collective name for all thermoplastic elastomers. Contains thermoplastic polyurethane TPU, thermoplastic polyester elastomer TPEE, thermoplastic dynamic vulcanization elastomer TPV, and styrene thermoplastic elastomer SEBS, SBS and its modified materials TPES.
TPR,thermoplastic-rubber. Refers to thermoplastic rubber.
In the Chinese region, TPE and TPR are usually referred to as styrene elastomer SEBS, SBS modified material TPES. Domestic users usually equate TPE and TPR as a material. However, domestic TPE manufacturers are used to The elastomer modified with the SEBS substrate is called TPE, and the elastomer modified with the SBS substrate is called TPR.
二. How to distinguish between TPE and TPR
The TPE and TPR mentioned here still refer to styrene series thermoplastic elastomers.
1. Appearance: TPE, the appearance is matte or sub-surface particles; TPR, the appearance is bright particles.
2. Combustion characteristics: TPE has a light aroma when burning, and the burning smoke is relatively small and light; TPR burning has a heavier smell, and the burning smoke is more and thick.
