Polytek 74 Series

Let’s shine the spotlight on one series from Polytek that shines for its flexibility, toughness and for the versatility of uses that our customers come up with for it: the Polytek 74 series.

Poly 74 Series polyurethane liquid mold rubbers are soft to mid-range hardness, high-performance, room-temperature curing systems. Count on these products to offer superior flexibility and toughness allowing durable molds to be made from relatively simple to highly detailed, complex models. The 74 Series liquid mold rubbers are supplied as pourable liquids but can be easily thickened to make brush-on molds.

Here are some of the features and benefits that you can expect from products in the Polytek 74 series.

• Room temperature curing (RTV).
• Two-part polyurethane rubbers.

One such sample from these Polytek 74 series is the popular Poly 74-20 Liquid Rubber.

Poly 74-20 is a pourable rubber, but it can be easily thickened. Whether you need a lot or a little for your projects, we’ve got you covered.
