What are the raw material classifications of heat insulating strips? We all know that the heat insulation strip material is polyvinyl chloride particles as raw materials, through the heat insulation strip extruder melting mold extrusion into the water cooling, according to the demand cut to size packaging. PVC heat insulation strip has the advantages of beautiful appearance, low price, so it is widely used in the field of broken aluminum. China's thermal strip market is divided into three levels:

1, The earliest to enter the Chinese market Taino wind BaoTai and other foreign imported brands;

2, In 2003, the domestic thermal bar began production, and the development of a number of high-quality national standard thermal bar manufacturers;

3, With the prevalence of broken-bridge aluminum doors and windows, the demand for thermal bar is also increasing day by day, more and more product categories, non-standard nylon thermal bar, PVC thermal bar to occupy a major market share.

Heat-insulating strips adopts professional extrusion technology, high strength, to meet the design needs, can ensure the long term stability of heat-insulating aluminum alloy doors and windows, framed curtain wall; heat-insulating strip linear expansion coefficient and aluminum profiles close to ensure that the heat-insulating strips in the sunshine and cold freezing conditions and aluminum lasting, close combination; heat-insulating strip processing temperature of up to 235 degrees, to fully meet the first through the strips after the spraying process; heat-insulating strips dimensional accuracy of less than 0.08mm, to ensure the airtight and watertight performance of the window.
