For repairing inflatable items, PVC (vinyl) patches are so far the most popular option. However, concerns have been raised on plasticised PVC, and some would prefer a good replacement for it. Thermoplastic polyurethane (TPU), one type of polyurethane plastics, might be the answer.
TPU has already been used widely in many industries. It is, among other things, a popular material used for making outer cases of mobile phones. TPU has many favorable physical properties, such as elasticity, flexibility, transparency, and resistance to oil, grease and abrasion.
With all the advantages, it is no surprise that self adhesive TPU patch is getting popular for inflatable repair in spite of higher cost. Here are five reasons to choose TPU patch over PVC patch.
#1 TPU patch exhibits good flexibility over a wide temperature range.
#2 TPU patch has high elasticity across the entire hardness range.
#3 TPU patch is suitable for repairing not only plastic but also rubber, leather, canvas, fiberglass, etc.
#4 TPU patch has great resilience to oils and greases and resistance to abrasion.
#5 TPU patch is “green” product with recyclability, biodegradable in soil after 3 to 5 years.
