Water Soluble Urethane

물에 잘 녹는 정도와 수분 흡수 능력(함수율)에 따라 다양한 제품 제공이 가능합니다.


그림1. 용제(Water, Ethanol, THF) 및 제조 방법에 따는 제품 분류도

Tecophilic® Hydrogel TPU의 종류

1. TG Grade

알콜과 물에 잘 녹는 제품으로 하이드로겔 마스크팩, water soluble film, 창상 피복 필름 등에 사용됩니다.

Type: Typical Physical Test Data – Hydrogel Grade, Medical grade aliphatic, polyether-based hydrogel TPUs
Features: Specially formulated to absorb equilibrium water contents of up to 900% of the weight of dry resin. This series can absorb or transport moisture. They have been designed to dissolve in various solvents for use in solution however they can also be melt coated or extruded.
Process: Solution casting, coating or extrusion

2. SP Grade

THF에 잘 용해되고 수분을 잘 흡수하는 특성으로 창상피복재 등의 필름에 이용됩니다.

Type: Typical Physical Test Data – Solution Grade, Medical grade aliphatic, polyether-based TPUs
Features: Specially formulated to absorb equilibrium water contents of up to 150% of the weight of dry resin. This series has been designed to be dissolved in various solvents for use in solution. The solution grades differ from the extrusion grades in that they contain no melt processing lubricants.
Process: Solution casting or coating

 

3. HP Grade

압출 및 사출 성형 제품이며 수분을 잘 흡수합니다.

Type: Typical Physical Test Data-Extrusion/Molding Grade, Medical grade aliphatic, polyether-based TPUs
Features: Specially formulated to absorb equilibrium water contents of up to 100% of the weight of dry resin.
Process: Extrusion primarily but can also be injection molded
