| titleOfInvention | Very soft polyurethane elastomer |
| abstract | FIELD: polymer production. n SUBSTANCE: invention relates to process of producing elastomeric polyurethane material having Shore hardness up to 5 (DIN 53505), density 500 kg/m 3 or higher (DIN 53420), compressive load (40%) deflection 600 kPa or less (DIN 53577), and elasticity 25% or less (ISO 8307). Process is accomplished by interaction of (i) polymethylene-polyphenylene-polyisocyanate with average isocyanate functionality 2.4 or more; (ii) polyol with average equivalent mass at least 500 and average nominal hydroxyl functionality 2-4; (iii) polyoxyalkylenemonool with nominal hydroxyl functionality 1 and average equivalent mass at least 500; and (iv) optional additives and auxiliary substances known per se in amount less than 5%. Reaction is carried out at index 90-110 and equivalent amount of polymer (iii) lies within a range of 25-80% based on accessible NCO equivalents. Elastomeric polyurethane material accordingly obtained is a soft gel-like material showing some degree of tackiness. Advantageously, this material is obtained using as little additives and auxiliary substances as possible, which results in reduced content of washed out products and residual reactive group in elastomeric polyurethane material. The latter can be employed in vehicle interior objects such as elbow-rests and instrumentation panels, in bicycle sittings, and in mouse tappets. n EFFECT: improved consumer's quality of elastomers. n 1 tbl, 12 ex |
