Pultrusion

Pultrusion is a continous method preferred in production of materials with specific mechanical properties in one direction. For example, structural profiles, rebars, posts and pipes of low diameter are produced with this production method. Polipol 3801, with its high reactivity and chemical resistance is preferred for production of gratings and structural profiles. Polives 711 is preferred for production of rebars and profiles. Polipol 3872 is used in road side delineator posts.

It is possible to produce unidirectional, rigid products with glassfiber ratios up to 70%.

Pultrusion Application

① Prepare a resin mixture with peroxide, internal release agent and filler.

② Impregnate glass fiber roving in the resin mixture in resin bath.

③ Guide impregnated glass fiber into the heated mold. Mold temperature should be adjusted to specific temperature values upon entrance (40-70°C), inside (80-110°C) and exit (140-170°C).

④ After the heating, the cured and molded profile is cut to specified dimensions.

Note: A high reactivity peroxide (percarbonates) called "kicker" is recommended in cooperation with a perester or perketal based peroxide which finishes the curing reaction.
