Multipurpose Flame-Retardant Garolite G-10/FR4 Sheets and Bars

A good all-around choice, these Garolite G-10/FR4 sheets and bars are strong, machinable, and electrically insulating. They're made of a flame-retardant epoxy resin with fiberglass fabric reinforcement. Garolite G-10/FR4 is also called epoxy-grade industrial laminate and phenolic.
Wear-resistant sheets are coated to stand up to rubbing and scraping better than uncoated sheets.
If you don't see the size you're looking for, please specify a length under additional bar lengths.

Static-Dissipative Multipurpose Flame-Retardant G10/FR4 Garolite Sheets

- Color: Yellow-brown to light green
- Max. Temperature: 355° F
- Tensile Strength: 35,000-50,000 psi (Excellent)
- Impact Strength: 5.5-12 ft.-lbs./in. (Excellent)
- Hardness: Rockwell M110 (Extra Hard)

With a black coating that reduces static electricity, these sheets are good for use in solder pallets, automated test equipment, electronic assembly workstations, and other applications where static buildup could damage your equipment. The coating is cured, so it won’t chip or peel off. These sheets are made of flame-resistant epoxy resin and are easier to machine than other glass-cloth phenolics. A fiberglass fabric reinforcement keeps them from breaking or cracking when bent.

Ultra-High-Temperature Impact-Resistant Garolite Sheets

- Color: Brown
- Maximum Temperature: 500° F
- Tensile Strength: 40,000 psi (Excellent)
- Impact Strength: 14-17 ft.-lbs./in. (Excellent)
- Hardness: Rockwell M115 (Extra Hard)
- For Use Outdoors: No
Resisting heavy impacts and temperatures up to 500° F, these Garolite sheets are used in machinery such as turbine bearings and downpipe gaskets. They’re alternatives to PEEK, Torlon, Ryton, and Ultem sheets.

Ultra-Low-Temperature Garolite G-10 CR Sheets

- Color: Green
- Temperature Range: -415° to 280° F
- Tensile Strength: 40,000 psi (Excellent)
- Impact Strength: 8-10 ft.-lbs./in. (Excellent)
- Hardness: Rockwell M110 (Extra Hard)
- For Use Outdoors: No
- Specifications Met: MIL-I-24768/2
Rated for temperatures down to -415° F, this Garolite G-10 CR performs better in cryogenic applications than other glass epoxies. An excellent thermal insulator, it’s often used to transport liquid gases. It also prevents the flow of electrical current. This Garolite keeps its shape without cracking when bent. It has a glass fabric base for strength.
