C122, C132, C142

Application example: Vacuum cleaner motor fan guide

Standard grade with glass fiber reinforcement and flame retardant level UL 94HB (1/32").

C122 is reinforced with 15% glass fiber, C132 is reinforced with 30% glass fiber, and C142 is reinforced with 40% glass fiber, and can be used depending on the required rigidity, load capacity, specific gravity, etc.

It has a low specific gravity and is second only to S105 in electrical properties such as high frequency characteristics and tracking resistance, and hydrolysis resistance. In addition, it has a good balance of mechanical strength, formability, and other properties, and can be used as a standard in electrical/electronic parts and a wide range of other application fields.

S131

Application example: Electronic Control Unit

30% glass fiber reinforced and registered to UL94HB. It is widely used in automotive electrical parts.

Zarec's UL746B certified temperature (℃)

grade		Electrical	mechanical

S131	H.B.	130	120	130

S135, S124

Can be used for food contact applications.

S136

Can be used for automotive electrical parts. Low gas specification.
