Rigid Glass-Filled Wear-Resistant
Easy-to-Machine Delrin® Acetal Resin Rods

A glass-fiber filler gives this material increased rigidity over standard Delrin® acetal resin. Use it to machine manifolds, impellers, and other parts that require rigidity.

Rigid Glass-Filled Wear-Resistant Nylon Rods

With glass reinforcement, this nylon 6/6 material is stronger than standard nylon, plus it can withstand higher temperatures. It’s widely used in high-stress applications, such as caster wheels and automotive parts.

High-Strength Glass-Filled
Impact-Resistant Polycarbonate Rods

The addition of glass fibers to this polycarbonate increases tensile strength for use in structural applications.

Durable Glass-Filled
Chemical-Resistant Slippery PTFE Rods

This glass-filled PTFE is more rigid than standard PTFE for increased durability in high-stress applications.

Durable Glass-Filled Chemical-Resistant
Slippery PTFE Tubes

This glass-filled PTFE is more rigid than standard PTFE for increased durability in high-stress applications.

Durable Glass-Filled Wear-
and Chemical-Resistant PEEK

A glass filler is added to this this PEEK material to offer increased durability over standard PEEK in high-stress structural applications.

Fiberglass

Structural FRP Fiberglass Rods

An alternative to wood in structural applications, FRP fiberglass is strong and lightweight.

Structural FRP Fiberglass Round Tubes

An alternative to wood in structural applications, FRP fiberglass is strong and lightweight.

Arc-Resistant GPO3 Fiberglass Rods

Offering excellent arc and track resistance, this GPO3 fiberglass is often used for electrical applications in humid environments.

Arc-Resistant GPO3 Fiberglass Round Tubes

Use these round GPO3 fiberglass tubes for electrical applications in humid environments.

Glass, Mica, Ceramic, and Graphite

Easy-to-Machine Glass-Mica Ceramic Rods

Machine complicated shapes and precision parts from these glass-mica ceramic bars in a fraction of the time it would take using other types of fired ceramic.

Very High-Temperature Easy-to-Machine
Glass-Mica Ceramic Rods

Also known as Macor, these glass-mica ceramic rods withstand temperatures up to 1470° F.

Borosilicate Glass Rods and Discs

Also called Pyrex and Schott glass, these glass rods and discs resist clouding and pitting and are highly chemical and heat resistant.

Pressure-Rated Borosilicate Glass Tubes

These short glass tubes can be used as glass bowls in oil dispensers.

Borosilicate Glass Tubes

Also called Pyrex and Schott glass, these glass tubes resist clouding and pitting and are highly chemical and heat resistant.

Borosilicate Glass Balls

Also called Pyrex and Schott glass, these glass balls resist clouding and pitting and are highly chemical and heat resistant.

Pressure-Rated Borosilicate Glass Discs

Commonly used as sight glass.

Ultra-High-Temperature
Quartz Glass Rods and Discs

Able to withstand temperatures up to 2100° F, this quartz glass is useful in high-temperature applications that also require optical clarity, such as high-intensity lighting, fiber-optic production, and optical lens systems.

Ultra-High-Temperature Quartz Glass Tubes

Blistering temperatures won’t melt these quartz tubes, and rapid temperature shifts won’t cause them to crack.
