PRODUCTO
MARLON ST
El policarbonato MARLON ST LONGLIFE
presenta, por lo general, una excelente resistencia
a la mayoría de los productos químicos. No
obstante, es difícil prever absolutamente todos los
factores a los que la plancha va a estar expuesta
La resistencia química no sólo depende del agente
químico, sino del grado de concentración, tiempo
de contacto, presión sobre el material, etc.
Las tablas de abajo muestran la resistencia del
policarbonato a 23 °C respecto a esos agentes
químicos. Estos compuestos son típicos para
muestras sin fuerza ni carga, expuestos
durante
6 meses en una solución del agente químico.
CLAVE :
+ buena resistencia
O resistencia limitada
- sin resistencia

se indican son en inglés, para evitar traducciones
