PP Multi Wall sheets
Signs - Outdoor and indoor illuminated signs
Displays - Exhibitions, commercial and industrial displays, etc.
Products - boxes, teaching aids, advertising aids, agricultural products - planters, flower boxes, etc.
Packaging - packages for special products, reusable packaging for food, pharmaceuticals, fragile materials, chemicals, trays, electronics etc.
Polygal PP Structured Sheets can be manufactured with protection against UV solar radiation by the addition of UV absorbing material.
A fire-retarding additive can be added to the sheet so that the flame retardancy level meets stringent standards. Polygal PP structural sheets meet UL 94 HB.
The treatment level (printing surface quality) of the Polygal PP structural sheets is measured according to ASTM D-2578. The standard level is 38 dyne/cm.
Service temperature: -5ºC to +85ºC
