Good flexibility
Aging resistance
As a "benchmark for temperature resistance and safety," silicone strips boast an extremely wide operating temperature range (-60℃ to over 200℃) and are non-toxic, odorless, and physiologically inert, meeting food-grade and medical-grade standards. While maintaining flexibility in extreme high and low temperature environments, their mechanical strength is relatively low and their cost is high, making them an ideal choice for sealing high-temperature appliances (such as oven door seals), medical devices, and infant products.
Key Advantages:

Extremely Wide Temperature Range:The widest of the three, typically operating stably from -60℃ to 200℃ (special models can reach over 250℃), exhibiting resistance to both high and low temperatures.
Excellent Chemical Inertness and Safety: Non-toxic, odorless, physiologically inert, meeting food-grade and medical-grade standards; excellent aging resistance.
Good Electrical Insulation: Remains stable over a wide temperature and frequency range.
Good Flexibility: Maintains excellent elasticity even at low temperatures.

EPDM adhesive strips
As the "King of Weather Resistance," EPDM rubber strips are renowned for their superior resistance to ozone, ultraviolet radiation, and heat oxidation. They maintain excellent elasticity and compression recovery over a wide temperature range of -40℃ to 120℃. Widely used in fields requiring extremely high long-term outdoor durability, such as automotive door and window seals and building curtain wall seals, they are the preferred material for withstanding wind and sun exposure, with a service life of up to decades.

PVC strips
As a cost-effective option, PVC strips are a low-cost thermoplastic material that can be customized with different colors and hardness levels. However, they have poor weather resistance, tend to harden and become brittle with prolonged outdoor use, and have a narrow temperature range (-10℃ to 70℃) and limited elasticity recovery. They are mainly used in indoor door and window sealing, furniture anti-collision strips, and other applications where lifespan and performance requirements are not high.

Colored and black compound rubber
As the "cornerstone of rubber product performance," compounded rubber is a key intermediate material formed by homogenizing raw rubber with various compounding agents through precise formulation and efficient mixing processes. It possesses highly customizable physicochemical properties. It provides a ready-to-use semi-finished product for subsequent molding processes such as calendering, extrusion, and compression molding, and is widely used in almost all rubber product fields, including automotive, construction, electronics, and medical industries. It is the core foundation that determines the quality and reliability of the final product.
