Our technical specialists, R&D chemists and compound laboratory are dedicated to creating innovative solutions for the ever-changing polymer industry; solutions that keep you ahead of your competition with increased productivity, better quality parts and lower overall cost. In addition to premium product performance, Struktol customer service initiatives have become the industry benchmark. 6 About Struktol company of america Struktol Products and their Use Struktol WB 222 is an ester of saturated fatty acids.
8 It is a highly effective lubricant and release agent predominantly used for polar elastomers. Struktol WB 212 is based on high molecular, hydrophilic fatty acid ester. The product serves as a dispersing agent for powdered materials and has excellent release properties. Struktol WB16 is an excellent lubricant mainly for non-polar rubbers. As a mixture of calcium soaps and amides of saturated fatty acids it can exhibit an activating effect. Struktol HPS 11 is composed of fatty acid derivatives, which have been designed and selected to give maximum polymer to additive interactions. HPS 11 is effective in increasing flow, promoting release, and improves overall processing. Struktol WB 42, a blend of fatty acid derivatives, provides improved flow in a wide range of elastomers.
9 Struktol W A 48 is successfully used in epichlorohydrin Rubber as an effective release agent and lubricant. Struktol W 34 is a dispersing agent and lubricant for nearly all elastomers. Faster filler incorporation and avoidance of filler agglomeration in highly filled compounds can be achieved. Struktol WS 180 and Struktol WS 280 are organosilicone compounds which combine outstanding release performance with good flow properties. Struktol WS 180 can drastically reduce mold contamination. Struktol ZB 47 is a formulated zinc soap that can be used for masticating NR. compounds. Also offers heat stability (Reversion Resistance). Very effective in mineral filled NR compounds. Struktol A 50, and A 60 are zinc soaps of unsaturated fatty acids.
10 They are mainly used as physical peptizers in NR compounds Struktol EF 44 A is a blend of fatty acid derivatives with zinc soaps predominating. The product is especially suitable for extrusions. It acts as a cure activator. Struktol HM 97 is a mixture of low viscosity polyethylene waxes. Due to their special lubricating effect, HM 97 is highly recommended in EPMD compounds. *For further information on ZB 47 contact Struktol for our new ZB 47 Brochure and CD. Lubricants 25.
