UP Pultrusion Profiles
Unsaturated polyester is the workhorse resin system of pultrusion: cost-balanced, fast-curing and well proven for general structural, electrical and corrosion-service sections.

Resin Note
UP is the economical general-purpose choice; isophthalic UP improves water and mild-chemical resistance. Choose VE where strong acid/alkali service is expected.
Applications
Common uses include support frames, cable ladder components, insulating supports, pipe and duct supports, truck/trailer parts, antenna supports, handrails and machine guards. See applications.
