ABS - acrylonitrile - butadiene - styrene. Thermoplastic. Very rigid and strong with good impact strength.
-20°C to
+60°C
inert to many chemicals
very good
PC - polycarbonate - Thermoplastic. Very rigid and strong with good impact resistance. Transparent options available. Well suited to higher temperatures.
-40°C to
+120°C
inert to many chemicals
good
LDPE - polyethylene - Low Density - Thermoplastic. Tough, light and resilient with good impact strength and recovery from distortion. Available in several grades.
-10°C to
+60°C
inert to many chemicals
extremely good
MDPE - polyethylene - A tough, slightly less flexible linear medium density. Thermoplastic with good impact strength and recovery from distortion. Suitable for wide temperature use.
-30°C to
+80°C
inert to many chemicals
extremely good
HDPE - polyethylene - High Density - Similar properties to low density, but harder and more rigid.
-30°C to
+80°C
inert to many chemicals
extremely good
PP - polypropylene - Thermoplastic. Similar properties to high density Polyethylene. Better suited to high temperatures and has a harder surface.
-10°C to
+100°C
inert to many chemicals
extremely good
SUPERPLAS - a thermoplastic material having excellent resistance to abrasion, good impact strength yet light in weight.
-10°C to
+100°C
inert to many chemicals
extremely good
Cleaning - Mailbox materials handling products are easily cleaned using a soda based detergent. Other detergents should not be used.
