As a specialized manufacturer in advanced polymer materials, Shanghai Yunshan Plasticizing Co., Ltd. proudly presents the SO-249-90A, a high-performance Thermoplastic Elastomer engineered for demanding applications. This grade represents our commitment to providing robust material solutions that combine the processing ease of plastics with the resilient properties of rubber. Specifically formulated to a 90 Shore A hardness, it delivers an optimal balance of flexibility and structural integrity, making it an ideal choice for parts that must endure repeated stress and wear in challenging environments.
The SO-249-90A TPE is designed to outperform conventional rubber and softer elastomers in applications requiring superior dimensional stability and longevity. Its high-performance characteristics stem from a carefully calibrated polymer composition that ensures consistent behavior across a wide temperature range. We understand that our clients in sectors like automotive, industrial machinery, and durable consumer products need materials that won't fail under pressure, and this product is our answer to that need, offering a reliable and cost-effective alternative to more expensive engineered materials.
Detailed Features & Technical Advantages:
Optimized Hardness Profile: The 90 Shore A rating provides a perfect middle ground—firm enough to maintain shape under load, yet sufficiently flexible to absorb impact and vibration without cracking.
Enhanced Durability: Formulated for high resistance to abrasion, tear, and compression set, significantly extending the service life of finished components compared to standard TPEs or rubber.
Excellent Processing Compatibility: Designed for seamless integration into standard thermoplastic processing equipment. It offers good melt flow for complex mold filling and fast cycle times, boosting production efficiency.
Superior Mechanical Properties: Exhibits high tensile strength and elongation at break, ensuring parts can withstand stretching and deformation without permanent damage.
Broad Chemical & Environmental Resistance: Provides good resistance to oils, greases, many aqueous solutions, and UV exposure, making it suitable for both indoor and outdoor applications.
Consistent Quality & Lot-to-Lot Uniformity: Manufactured under strict quality control protocols in our Shanghai facility, ensuring every batch meets precise specifications for hardness, color, and performance.
Key Technical Specifications:
Benefits for Your Business:
Reduced Total Cost: The durability of SO-249-90A leads to fewer part failures and replacements, lowering long-term maintenance costs for end-users.
Design Freedom: Its thermoplastic nature allows for the creation of complex, multi-material components (e.g., overmolding onto rigid plastics) that are impossible with thermoset rubbers.
Production Efficiency: Faster processing cycles and the ability to recycle scrap material directly translate to higher output and reduced material waste.
Reliable Supply: Sourced and produced locally in Shanghai, we ensure stable supply chains and responsive technical support for our partners.
Choosing a material supplier is a critical decision for any manufacturing operation. At Shanghai Yunshan Plasticizing, our expertise is grounded in years of focused development within the polymer industry, serving a diverse clientele that trusts us for consistent, high-quality materials. The SO-249-90A is not just a product; it's a testament to our capability to deliver engineered solutions that meet precise performance criteria. By opting for this high-performance TPE, you are selecting a material backed by professional technical knowledge and a commitment to partnership. We invite you to request a sample to test its properties against your specific application requirements or to contact our technical team for a detailed consultation on how SO-249-90A can enhance your product's durability and performance.
Frequently Asked Questions (FAQ):
Q: What is the main difference between this 90A TPE and a traditional rubber like NBR or EPDM?
A: Unlike thermoset rubbers that cure irreversibly, SO-249-90A is a thermoplastic. This means it can be melted and re-processed, allowing for faster production cycles, recyclability of scrap, and the ability for advanced overmolding processes.Q: Is this material suitable for outdoor applications exposed to sunlight and weather?
A: Yes, this TPE grade is formulated with good UV and environmental resistance. However, for critical long-term outdoor exposure, we recommend discussing your specific requirements with our team, as optional UV stabilizers can be incorporated.Q: Can the color be customized?
A: Absolutely. While standard offerings are available in black and natural, we provide extensive color matching services to meet your product's aesthetic needs.Q: What types of processing equipment are compatible with SO-249-90A?
A: It is designed for use with standard thermoplastic processing equipment, including injection molding machines and extruders. Optimal processing parameters (temperature, screw speed) will be provided upon request.Q: How does the 90A hardness compare in terms of feel and performance?
A: A 90 Shore A hardness feels firm yet slightly flexible—similar to a hard rubber eraser or a car tire tread. It offers excellent load-bearing capacity and resistance to deformation under force.Q: Is this material resistant to oils and chemicals?
A: It offers good resistance to non-polar substances like oils and greases typically encountered in automotive and industrial settings. For specific chemical resistance needs, please consult our technical data sheet.Q: Do you provide material data sheets and samples for testing?
A: Yes, comprehensive technical data sheets (TDS) are available for download or upon request. We also encourage potential clients to evaluate performance firsthand through our sample program.Q: What is the typical lead time for an order?
A: Lead times depend on order quantity and customization. For standard grades and colors, we often maintain stock for prompt shipment. Specific timelines can be confirmed upon inquiry.
