Modified polyvinyl chloride composition |
摘要 |
Finished articles made of flexible polyvinyl chloride (PVC) using plastisol technology are improved in terms of resistance to heat and solvents and reduction in plasticizer migration by incorporating into the traditional plastisol ingredients substantial amounts of blocked di- or polyisocyanates and di- or polyols and/or di- or polyamines, which, upon heating react with each other to form a polymer network within the article while the PVC is gelling.
