PVC profile products have gone through a period of import and rapid development

PVC profile products have gone through a period of import and rapid development, which can be defined in terms of time as the mid-1980s and 1995-2002 respectively. After 2003, the PVC profile industry entered a period of transformation. During the product introduction period, manufacturers generally pursue low cost, simplify the cross-section of door and window profiles, and fill a large amount of calcium carbonate in the formula, resulting in low product performance. The emergence of many quality problems has affected the promotion of the product.
Since 1995, a group of powerful enterprises have begun to digest and absorb the technical essence of foreign European profiles, and developed their own door and window series, which has become the leading role of domestic plastic doors and windows, promoting the technical update and development of doors and windows, and also making the entire industry get unprecedented development and rapid growth. After entering the mature stage of the product, that is, since 2003, many drawbacks began to be reflected. The excessively high profit margin led to blind investment, resulting in a comprehensive production capacity of nearly 3 million tons in the industry, far exceeding market demand; Many new investors who enter the market do not start with product innovation or technological innovation, but simply imitate, even cut corners, counterfeit and shoddy products, and the industry market competition is in an unhealthy state. The continuous rise in raw material market prices has intensified this unhealthy competition, causing some enterprises to face difficulties in their operations, resulting in shutdowns or semi shutdowns.
