3.About three-quarters of all vinyl produced goes into long-lasting building and construction applications..
4.Vinyl helps produce siding and window frames that are extremely durable, affordable, and help conserve energy when heating and cooling homes. In fact, vinyl windows have three times the heat insulation of aluminum windows..
5.Wiring and Cables
Vinyl is able to withstand tough conditions behind building walls – such as exposure to changing temperatures and dampness – for the life of the building.
6.Vinyl plays a critical safety role in dispensing life-saving medicine through IV bags and medical tubing..
7.PVC’s affordability, durability and water resistance make it ideal for rain coats, boots and shower curtains.
