Shuntai Technology has developed a diversified range of blowing agent products based on market demand, encompassing three major categories: general-purpose, eco-friendly, and specialty types. These agents precisely match various substrates including EVA, PE, PVC, TPR, and rubber, and are widely applied across multiple vertical sectors such as automotive, footwear materials, packaging, sports equipment, and construction. We provide customers with comprehensive “one-stop” blowing agent solutions.
Representative products include the SA series, such as SA1000, SA3000, SA5000, SA6000, and SA7000.
Chemical formula C₂H₄N₄O₂, molecular weight approximately 116.079.
Appearance: Light yellow powder, density approximately 1.65 g/cm³.
Excellent compatibility for use in plastic and rubber systems.
Different grades vary in particle size, gas yield, decomposition temperature, etc., to meet diverse processing requirements.
SA1000: Particle size 10-15 µm, decomposition temperature approx. 205 ± 5 °C, gas yield approx. 225 ± 5 ml/g. Suitable for conventional plastics like EVA, PE, PVC.
SA3000: Particle size 8-10 µm, finer grade ideal for products requiring smooth surfaces and precise cellular structures.
SA5000: Particle size 6-8 µm, specifically designed for thin sheets and high-precision foamed products.
SA6000: Particle size 4-6 µm, suitable for precision structural components, small packaging, and automotive seals.
SA7000: Particle size 3-5.5 µm, the highest-end specification, used in automotive interiors, premium plastic cushioning, and similar applications.
Plastic Packaging & Electronic Product Cushioning Materials: Utilize high gas yield to reduce density and enhance cushioning and shock absorption performance.
Building Materials Plastics: For PVC foam boards and PE insulation boards, achieve lightweight construction and improved thermal/acoustic insulation through the use of AC foaming agents.
Automotive plastic interiors: Requiring high environmental standards (low VOC) and high dimensional stability, the SA5000/SA7000 models meet these demands.
Fitness and sports equipment plastics: Such as yoga mats and footpads, achieving lightweight properties and excellent elasticity through uniform cell structure.
Stable foaming performance with excellent batch-to-batch consistency.
High gas release rate reduces usage and lowers costs.
Adjustable decomposition temperature adapts to various processing methods.
Non-corrosive and non-staining protects equipment and molds while maintaining product appearance.
These products are based on standard AC and undergo modification processes—such as enhanced temperature resistance, reduced decomposition temperature, finer particle size, and adjusted gas yield—to suit specific materials or processing conditions.
For low-temperature processing plastics or PP, and high-temperature processing plastics.
For products requiring finer cell structure and high surface smoothness.
Example: SA5000D is a modified AC foaming agent with a low decomposition temperature (approximately 145 ± 5°C).
Advantages: Meets differentiated needs, delivers higher added value, and enhances product performance differentiation in highly competitive industries.
Shuntai-NC-6 Model: White powder suitable for PVC blow molding and injection molding foaming. Provides PVC shoe soles with excellent whiteness, color, and uniform bubble structure.
Shuntai-NC-2 Model: Used for foaming PVC, PE, and PS products, resulting in more uniform cell structure and superior whiteness.
Appearance: White powder. Suitable for products with high color requirements (e.g., light-colored or white soles, PVC footwear materials, toy plastic components).
When used in combination with AC foaming agents, it enhances bubble uniformity and improves product appearance quality.
Applications: Footwear materials (white soles), children's toys, decorative materials, lightweight sheets, etc.
OBSH is an organic compound widely used for foaming in the rubber and plastics industries.
Characteristics: Suitable for applications requiring low decomposition temperatures, high cell structure requirements, or rubber systems. Strict safety protocols must be followed during handling.
Applications: Rubber products (e.g., seals, gaskets), plastic foam materials, specialty foam products.
Features:
High gas yield, suitable for applications requiring high foaming performance or large expansion ratios.
Compatible with various raw materials (rubber, synthetic rubber, plastics such as PVC, PE, PS, ABS, etc.)
Applications: Footwear materials (soles, insoles), rubber products, tubing, seals, foam plastic sheets.
Features:
Masterbatch formulation facilitates processing, metering, and blending, making it ideal for automated production.
This eco-friendly masterbatch emphasizes low odor, low residue, and compliance with environmental regulations (such as REACH, ROHS, etc.).
Applications: Automated injection molding, extrusion, blow molding, and sheet production lines. Particularly suited for packaging, children's products, medical device linings, and other applications with stringent environmental requirements.
Core-shell structure, with the outer shell typically composed of thermoplastic polymers and the inner core consisting of low-boiling-point organic gases. When heated, the shell softens and the gas expands, producing a foaming effect.
High expansion ratio, suitable for lightweight materials, easily processed products, and items requiring high surface quality.
Applications: Toys, sports equipment, lightweight furniture panels, packaging materials, lightweight concrete, or composite materials.
