Two part liquid polyurethane taxidermy supplies with low viscosity and a variety of different physical properties. Poly 75-90 Liquid Rubber is a two-part, liquid polyurethane system that cures (RTV) to a tan, Shore A90 rubber. The elastomers exhibit low viscosities and are easy to process and cure. Rodgers, in Encyclopedia of Materials: Science and Technology, 20015.8 Polyurethane Polyurethane coatings used for marine coatings are made from resins that contain the isocyanate group and are highly reactive with compounds that contain hydroxyl groups (e.g., water and alcohols) which are commonly used for curing agents. Parts cast IE Series Urethane Elastomers Use these polyurethane balls as seals in pumps and check valves or let them bounce inside of vibrating sifters for an effective screen cleaner. Poly 75-80 Liquid Rubber is a two-part, liquid polyurethane system that cures (RTV) to a yellow, Shore A80 rubber. LEO-80A 年式 2020 芯間-仕様 ＜ 精度更生機 2020年5月完成予定 ＞ ベッド上の振り:490 mm 往復台上の振り:260 mm 主軸端:A1. H. Bleile, S.D. This scale or chart is in the Shore A range which most rubber materials fall under. Urethanes 55A to 80A durometer can be ground successfully in an engine lathe using a tool post grinder. This system is recommended to applications in which the part requires high rebound, slide TDS Product Ratio by Weight Ratio by Volume Mixed Visc Gel Polyurethane Type L42 L100 L167 L315 Hardness, Durometer Value (ASTM d676-59T) 80A 90A 95A 75D* Specific Gravity 1.07 1.10 1.13 1.21 Tensile Strength, MPa (psi) (ASTM D412-61T) 20.7 (3,000) 31.0 (4,500) 34.5 (5,000) Three Polyurethane Machining Processes Milling is used when parts that can’t be machined in a lathe or when close tolerances and a good surface finish are required. High Performance Polyurethane Cast Elastomer System 80A, This is a PTMEG/MDI base high-performance polyurethane casting system. This is the hardest rubber in the 75-Series line of polyurethane mold rubbers. 3–6 Failure of the polyurethane insulation in unipolar leads was shown to be caused by ESC. Use low turning speeds - below 150 rpm, with the lathe running in reverse.
