Product Overview
PVC paste resin, as its name indicates, is specifically formulated for applications requiring a paste-like consistency. This resin is primarily utilized in plastisol formulations-a viscous liquid suspension of unprocessed PVC particles dispersed in plasticizers. These resins are typically synthesized through emulsion or micro-suspension polymerization techniques, which optimize particle size and distribution for stable, high-performance paste behavior.

Application Guide
Foaming Applications Type
Core Characteristics:
1. Low viscosity and high filling: maintains excellent fluidity even under high filler loading, suitable for complex formulation processing.
2. Efficient chemical foaming: realize uniform closed cell structure in chemical foaming system (e.g. AC blowing agent), high expansion ratio.
3. Excellent foam whiteness: reduce the amount of titanium dioxide added, reduce raw material costs.
4. High expansion stability: not easy to collapse in the foaming process, accurate density control of finished products (0.15-0.25 g/cm³).
Typical applications:
1. Decorative materials: foam wallpaper, relief coating.
2.Printing ink: high covering power flexible ink, suitable for packaging printing.
In the foam wallpaper, PVC paste resin through the chemical foaming process to form a uniform three-dimensional relief texture, soft to the touch and pattern layers, while significantly reducing the density of the material, so that the wallpaper weight reduction of 30% -40%, to enhance the ease of construction and transportation efficiency; its high coverage and whiteness can completely cover the grass-roots wall defects, reduce the amount of pigment, and excellent compression and resilience and fire-retardant properties to ensure that long-term use is not easy to deform or safety hazards. Its high hiding power and whiteness can completely cover the defects of the base wall and reduce the amount of pigment. In addition, the low-temperature foaming process and compatibility of formulations further optimize production energy consumption and costs. Compared with traditional wallpaper, the unibody structure avoids the complexity of multi-layer lamination, reduces the breakage rate, and broadens the applicability of high-end decorative markets.
General Purpose
Core Characteristics:
1. Low viscosity and easy processing: suitable for high-speed coating and impregnation process, shorten the production cycle.
2. Highly transparent and glossy surface: reduce the steps of surface treatment, directly obtain the mirror effect.
3. Strong mechanical properties: tensile strength ≥12 MPa, elongation at break >250%, excellent durability.
Typical applications:
1. Synthetic leather: car seat skin, high-grade furniture leather (through the transfer process of release paper).
2. Automotive sealing materials: windshield sealant, body seam filler.
3. Industrial flooring: wear-resistant coating, anti-static flooring.
In typical applications such as synthetic leather, automotive sealing materials and industrial flooring, general-purpose PVC paste resins, with their high mechanical strength and processing adaptability, are used as the core substrate to give the products multiple advantages: in the field of synthetic leather, the texture of the leather is accurately reproduced through the transfer process of the release paper to provide a high-gloss surface and abrasion resistance, avoiding frequent repairs, and the service life of the product is over 30% longer than that of the traditional material; in automotive sealing, the In the automotive sealing, low viscosity characteristics to ensure dense filling of complex gaps, cured to form a temperature-resistant (-40 ° C ~ 120 ° C) elastic layer, effectively blocking noise and leakage; and industrial flooring, high filler formulations combined with carbon fiber and other additives, the formation of hardness of up to 4H wear-resistant coatings, antistatic can be more stable to maintain the surface resistance (10 6 ~ 10 9 Ω), to prevent the damage of electronic components, and simplify the construction process, reduce the overall cost. At the same time, it simplifies the construction process, reduces the comprehensive cost, and meets the long-lasting demand of harsh industrial environments.
