NBR/PVC保温材料使用丁腈胶粉降低成本

Customer name: Zhejiang Rubber Products Co., Ltd.

Product selection: Fortune 120 mesh black and white nitrile rubber powder

Use occasion: mixed with nitrile rubber / PVC insulation material

Case background: Foam insulation materials processed from nitrile rubber and polyvinyl chloride as main raw materials have low thermal conductivity, high flexibility, heat resistance, flex resistance, sound absorption, shock absorption, waterproof, flame retardant, which can be significantly reduced Hot and cold loss. In recent years, China's construction, chemical, pharmaceutical, textile, metallurgy, electrical appliances and other industries have increasingly demanded insulation materials. The majority of rubber product manufacturers are rushing to produce NBR / PVC insulation materials to meet market demand. Manufacturers have a large inventory backlog of raw materials and finished products.

Case overview: Zhejiang Rubber Products Co., Ltd. operates various rubber pads, rubber and plastic strips, rubber foam hoses, rubber sheaths, etc. NBR / PVC insulation materials are a new product launched by the plant to cater to market trends and expand the market product. However, due to excessively fierce market competition, new product production costs are high, prices and reputation are not dominant, and sales are not ideal, resulting in a large backlog of finished products and raw materials, decided to use nitrile rubber powder in raw materials, appropriately reduce rubber and plastic insulation Material production costs.

After many comparisons and tests, the customer decided to mix NBR / PVC insulation materials with nitrile rubber powder, which significantly reduced the production cost by about 35% on the premise of ensuring quality; after the high cost performance insulation materials were introduced to the market again in the later period , Market sales are rising steadily.

Performance requirements: The biggest feature of foam insulation materials is thermal insulation, which requires low thermal conductivity, low water absorption, and the skin is not easy to penetrate water vapor. It has good flexibility and easy installation. In theory, when rubber powder is used in rubber products, the higher the fineness, the better the application effect. When adding nitrile rubber powder 2LLYY529 to the NBR / PVC insulation material, the fineness and impurity content of the nitrile rubber powder will affect the compactness, gas permeability resistance and water absorption of the foamed insulation material. The nitrile rubber powder can be evenly dispersed in the rubber-plastic blending material, and has almost no effect on the mechanical strength, compactness, gas permeability resistance and water absorption of the foamed material.

Reason for selection: Hongyun 120 mesh nitrile rubber powder has small particle size and no impurities, and has the characteristics of heat resistance, cold resistance, abrasion resistance, solvent resistance, strong flexibility, etc .; good compatibility with rubber and plastic materials, polymer melt The stability is extremely high, and the proper amount is mixed with NBR / PVC foam insulation material. The finished product has uniform foaming and dense texture. It is difficult for external moisture to penetrate into it, and it can maintain excellent insulation performance for a long time.

Experiments show that the processing performance of foam insulation materials mixed with nitrile rubber powder is better than that of NBR / PVC rubber-plastic materials without rubber powder.

Use effect: Hongyun 120 mesh nitrile rubber powder has two colors of black and white. The customer filled black nitrile rubber powder when preparing dark NBR / PVC foam insulation material, which can reduce the production cost by about 35% on average, and the cost performance is more High; 120 mesh white nitrile rubber powder is used when preparing white, light-colored, and colored thermal insulation materials. It is easy to match colors, to a certain extent, it can also prevent plasticizer from migrating, and can reduce production costs by 29% on average.
