In the demanding world of rubber manufacturing, selecting the right polymer is the cornerstone of product success. Skyprene general-purpose grades offer a versatile and high-performance lineup tailored for diverse industrial applications.
By leveraging raw rubber with high Mooney viscosity, these grades significantly enhance key mechanical properties, including modulus, tensile strength, and tear strength. Let’s dive into the unique characteristics of each grade to help you find the perfect match for your production needs.
Skyprene General-Purpose Grades
Type: Mercaptan-modified, general-purpose grade.
Key Features: Characterized by a medium rate of crystallization and moderate Mooney viscosity (49). It delivers an excellent balance of heat resistance, oil resistance, weather resistance, and outstanding storage stability.
Type: Low-viscosity variant of B-30 (Mooney viscosity: 42).
Key Features: Thanks to its lower viscosity, B-31 boasts superior fluidity and dimensional stability. It reduces heat generation (low calorification) during mill mixing, which stabilizes Mooney scorch and minimizes mixing issues.
Ideal For: Extruding, calendering, and injection molding.
Type: High-viscosity counterpart to B-30.
Key Features: With a high Mooney viscosity of 127, Y-30S allows manufacturers to incorporate large amounts of filler or oil, effectively driving down formulation costs. It can also be blended with other grades to improve processability.
Ideal For: Adhesives and heavy-duty rubber products.
Type: Low-viscosity variant of Y-30S (Mooney viscosity: 100).
Key Features: It retains the core benefits of the Y-series but offers significantly better processability and fluidity than Y-30S.
Type: Xanthogen-modified grade.
Key Features: Engineered for demanding environments, P-90 provides high mechanical strength and high modulus. Its crystallization rate is slightly faster than the B-30 series.
Typical Industrial Applications
Skyprene general-purpose series is widely used in:
Automotive Parts: Hoses, seals, and anti-vibration rubber components.
Industrial Rubber Goods: Belts, rolls, and heavy-duty conveyor lining.
Electrical Infrastructure: Wire and cable jacketing requiring reliable weather and oil resistance.
