What is a LPL panel?
LPL (Laminat, Polietylen, Laminat)
The LPL panel that we are using in production of our affordable houses is composed of 3 layers:
- Polyurethane foam (PUR, PIR)
- Polyester?glass laminate (PS)
- Polyester?glass laminate (PS)
Facts
Laminates are materials created by combining fibers with adhesive binders. Fibers make up the frame, and adhesive binders, which are mostly resin, combine the fibers together. Excellent adhesion of the resin with the fibers are the reason behind the product?s special characteristics, mechanical strength, light weight and resistance to corrosion, etc. It does not require complicated technologies and production processes.
Closed-cell (min.95%) polyurethane foam, is created by combining two liquid ingredients: polyol and isocyanate in a 1:1 ratio, called MDI in short. In this way, a reactive mixture is created. In effect of gassing, within about 10 seconds, the micture starts to foam creating heat that causes it to harden. The final result is a closed-cell hard and firm structure.
Polyurethane foam is an ecological and safe material.
History
Polyurethane foam as well as laminates are successfully used on an industrial scale for over 50 years.
Laminates were used for many centuries. Using laminates initiated in China with a material known as Chinese lacquer or varnish.
The real expansion in production of laminates(composites) on an industrial scale started in the mid 1940?s. Since then, assortment and variety of chemical materials used in production of resins expanded greatly.
This had a significant impact on development of new production technologies of polyester resins and combining them with fibers like glass fiber and carbon fiber.
