Insufficient Chemical Resistance of PCTG Products
Fenómeno do problema
PCTG products swell or crack after contacting certain chemicals.
Análise das causas
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.
Solução
Evaluate the chemical exposure risk of the use environment; anneal the products to reduce stress; select more chemical-resistant materials when necessary.
Conclusão principal
The chemical resistance of PCTG is good but limited.
