Insufficient Chemical Resistance of PCTG Products
문제 현상
PCTG products swell or crack after contacting certain chemicals.
원인 분석
Although PCTG has better chemical resistance than PETG, it is still sensitive to certain solvents (such as ketones, aromatic hydrocarbons, etc.), and is more prone to cracking in the presence of stress.
해결 방법
Evaluate the chemical exposure risk of the use environment; anneal the products to reduce stress; select more chemical-resistant materials when necessary.
핵심 요약
The chemical resistance of PCTG is good but limited.
