Customer information: Hebei Sealing Products Co., Ltd. is committed to research new waterproof, shock-absorbing sealing materials, the main production of butyl single-sided sealing tape, used for sealing all kinds of daily necessities, such as the sound speaker seal, reinforcement, shock absorption, sound-absorbing, Refrigerator, air-conditioning seal, anti-noise, as well as kitchen, bathroom walls and walls, tub sink and wall sealing and bonding, etc., product waterproof performance, sealing effect, sound absorption shock absorption effect is good, deeply favored by customers. In order to reduce the cost of raw materials, the customer in order to reduce the cost of raw materials, the single-sided sealing tape products were produced by the use of the proprietary butyl reclaimed rubber and butyl rubber, which greatly reduced the cost of raw materials in the case of satisfying customer needs.
Performance requirements for single-sided sealing tapes: butyl regenerated rubber raw materials used for producing single-sided sealing tapes have good physical properties such as waterproofness, adhesiveness, elasticity, and elongation, as well as excellent chemical stability, corrosion resistance, and weather resistance. , Electrical insulation, has a certain sound absorption and shock absorption performance, in order to ensure the product's performance and service life.
Hongyun High-strength Butyl Recycled Adhesive Features: The product is based on Taiwan's famous waste butyl inner tube. Compared with other butyl reclaimed adhesives, 5% butyl rubber is added in the production, which has strong air tightness, heat resistance, Ozone resistance, anti-aging, chemical resistance, shock absorption, electrical insulation, high strength, good feel elasticity, environmental protection and tasteless characteristics; detection of average parameters with 45% gel content, tensile strength 9.2Mpa, elongation at break The rate is 520% and the Mooney viscosity is 50±5 degrees.
Good luck and high strength butyl reclaimed rubber defects: Although Hongyun High-strength butyl reclaimed rubber has better performance and higher specifications than other butyl reclaimed rubber, all indicators are comparable to those of previously used butyl rubber. For a certain gap, all butyl single-sided sealing tapes produced using HYF's high-strength butyl reclaimed adhesives have reduced their elasticity and service life.
Solution: In order to solve this problem, the customer has, after several trials, decided to add a small amount of butyl rubber to the butyl single-side sealing tape formulation to improve the deficiencies of the butyl regenerated rubber product.
Usage effect: The butyl single-sided sealing tape produced by the use of Ford-butyl butyl reclaimed rubber and butyl rubber has excellent waterproof performance. It is used for sealing in kitchens and other places where the adhesive surface has strong adhesion and good sealing effect. In all types of electrical and electronic products, the chemical properties are stable, not only has a good sealing effect, the absorption effect of the absorption surface of the adhesive surface is significant; the product has good elasticity and large tensile strength, and can be adapted to the sealing of various shapes. According to the feedback of the customer, after using the high-strength butyl reclaimed adhesive, the raw material cost of the butyl single-sided sealing tape product was reduced by about 30%, and the product performance could meet the customer's demand and brought more orders for the manufacturer.
