The hardness of PVC materials is a core indicator affecting the structural strength of finished products, assembly effects, and operational stability. Batch fluctuations in hardness directly lead to inconsistent hardness in finished products, varying tigh

Standardized general PVC materials cannot be adapted to all non-standard, special, and refined production scenarios. Custom modification is the core method to solve special working conditions, new product development, and non-standard equipment adaptation

Recycled black PVC material is produced through resource recycling and modification technology, offering outstanding cost-performance and good structural stability, aligning with the concept of circular economy and being widely used in the general industr

During the long-term continuous production process on an extrusion line, issues such as fluctuating discharge speed, uneven thickness, surface undulations, and dimensional variations in the profile are common problems in extrusion processes. These not onl

The formation deformation, warping, and dimensional deviation of rigid PVC pipe fitting products are frequent issues in pipe fitting production, primarily manifested as pipe bending, uneven ends, dimensional shifts, and continuous deformation after demold

In the production process of transparent PVC products, hazy appearance, black spots, white spots, fine impurities, and crystallization points are relatively common surface defects, which directly affect the transparency and market quality of the finished

There is no unified and fixed grading standard for the environmental grade of PVC raw materials. The industry mainly distinguishes them based on testing items, controlled components, compliance standards, and applicable regions. The environmental entry ru

In the actual production and processing of plastics, whether the PVC raw material selection matches the production process directly determines the molding fluidity, finished product yield, and overall quality of the finished product. Most production defec
