As a company deeply rooted in the rubber industry, Dalian Bohai Rubber & Plastic Co., Ltd. has a profound understanding of the harsh environmental conditions that typically prevail in Northeast China starting from November. The sudden drop in temperature and the onset of icy and snowy weather present a formidable challenge to the performance of rubber products. Yet, we remain committed to delivering customers innovative, independently developed material technologies—providing rubber solutions that maintain stability and reliability even under extreme conditions.

1. Precise Insight: The Core Mechanism Behind How Low Temperatures Challenge Rubber Performance

The low-temperature environment in Northeast China during November essentially pushes rubber materials to the brink of their performance limits. The core challenge lies in:

1. Glass Transition: When the ambient temperature drops below the glass transition temperature (Tg) of the rubber, segmental motion of the polymer chains becomes "frozen," causing the material to shift from a highly elastic state to a glassy state, characterized by hardening, increased brittleness, and a complete loss of elasticity.
2. Crystallization Tendency: For materials like natural rubber (NR), sustained low temperatures can induce the ordered arrangement of molecular chains into a crystalline structure, further exacerbating material hardening. This leads to a range of issues, including sealing failure and deterioration of shock-absorbing performance.

II. Our Solution: A Self-Developed Low-Temperature Formulation System

Facing this common challenge in the industry, our company has successfully developed a next-generation cold-resistant rubber formulation system, leveraging our independently developed platform. The key breakthrough lies in:

• We prefer polymer matrices: We use specialty synthetic rubbers with low glass transition temperatures (Tg), such as BR and EPDM, as the primary materials to inherently enhance the product's cold-temperature resistance.
• Innovative plasticizing system: By blending a highly efficient, self-developed low-temperature-resistant plasticizer, the system effectively inserts itself between rubber molecular chains, inhibiting interactions among chain segments. This significantly lowers the material's glass transition temperature and crystallization tendency, ensuring that the product maintains exceptional flexibility even at -40°C and below.
• Optimizing the vulcanization and reinforcement system: Precisely controlling the crosslink density and selecting appropriate reinforcing fillers to maximize the material's elastic recovery capability and dynamic fatigue resistance at low temperatures, while ensuring the necessary strength and abrasion resistance.

III. Program Outcomes: Infusing "Cold-Resistant" Genes into Diverse Application Scenarios

Leveraging the core technologies mentioned above, our products can better tackle the challenges of Northeast China's autumn and winter seasons:

• High-performance sealing products: Our cold-resistant gaskets, O-rings, and other products maintain their flexibility and elasticity even at low temperatures, effectively addressing sealing leaks and unwanted noises in vehicles, electric motors, and industrial equipment.
• Specialty rubber components: Custom-made rubber protective covers, shock-absorbing pads, and more designed for outdoor equipment and specialized vehicles, delivering exceptional impact resistance and crack-proof performance even in freezing temperatures—ensuring stable operation of your equipment.
• Material Support: The specialized low-temperature adhesive materials we provide have also offered crucial material support to our industry peers in the region, collectively helping to elevate the overall industry standards.

Conclusion:

Only by understanding the cold can we truly conquer it. Dalian Bohai Rubber & Plastic Co., Ltd. will always remain committed to driving innovation through technology, continuously deepening our research into the behavioral mechanisms of rubber materials under extreme conditions. Through consistently refined, high-quality formulations, we transform challenges into reliable strengths for our products—empowering every customer to face even the harshest cold with confidence and steady progress.
