El polipropileno de copolímero de Polystone® P ofrece una excelente resistencia química y se mecaniza, fabrica y se suelde fácilmente. El copolímero ofrece una mayor resistencia de impacto que el homomolímero PP, especialmente en temperaturas frías tan bajas como –40 ° F.
Propiedades clave
Resistencia química
Costo relativamente bajo
Mejor fuerza de impacto que el homo-polímero PP
Limitaciones
Menor fuerza de impacto que HDPE
Mala resistencia a los solventes aromáticos, alifáticos y clorados.
Aplicaciones
Tanques estructurales y revestimientos
Barriles
Conductos y capuchas de humo
Equipo de procesamiento de semiconductores
Dispositivos ortescendientes y protésicos
Componentes de la bomba y la válvula
