Wiki Article
Even though efficient, these stabilizers pose important challenges when PVC is disposed of or recycled. Lead contamination in PVC squander will make recycling tough and poses prolonged-expression environmental dangers.
PVC usually includes a very low level of thermal steadiness. Having said that, stabilizers can enhance this by stopping polymer degradation beneath processing or mild exposure disorders.
Hanno migliori valori di isolamento e sono in grado di ridurre i costi energetici e di riscaldamento, inoltre sono di facile manutenzione.
PVC’s exclusive mixture of Houses has built it a most well-liked option for a myriad of apps. Right here’s an overview:
The carbon-chlorine bonds in the vinyl chloride models give PVC its distinct Houses, such as resistance to environmental aspects and electrical insulation.
