Thermoplastic Elastomer Sealing Strips
Boasting excellent elasticity, superior wear resistance, good oil resistance, and a wide adjustable hardness range (Shore A hardness 65-80 degrees), this material exhibits superior mechanical properties (tensile strength, elongation at break). It also features excellent cold resistance and resistance to chemical corrosion. The raw material costs are higher. It is recyclable and reusable. The operating temperature range is -60 to +80°C. Suitable for areas prone to earthquakes, near railways, or in factories with heavy-duty cranes, where strong vibrations occur, as well as regions with intense ultraviolet radiation.
Thermoplastic Vulcanizate (TPV) Sealing Strips
Rubber-soft and elastic, this material can be produced using plastic processing methods without vulcanization, with waste recyclable and reusable. It's a material with a wide performance range, boasting good heat and cold resistance, a low relative density, and similar oil and solvent resistance to rubber. However, it's not as good in resistance to compression deformation and wear. The operating temperature range is -40 to +150°C. Suitable for cold environments and mid-to-high-rise buildings.
The material is inexpensive and readily available, offering corrosion, wear, acid and alkali resistance, as well as resistance to various chemical mediums and combustion. It boasts high mechanical strength. However, it has drawbacks such as the tendency of plasticizers in the system to migrate, leading to hardness and brittleness over time, loss of elasticity, poor aging resistance, and inadequate weathering and low-temperature performance. It is typically used for dark-colored products and is suitable for environments with low light, minimal temperature variations, and non-severe climatic conditions.
Surface Coating Materials
Coating the sealant surface with materials instead of the traditional surface flocking process. The coated sealant exhibits excellent wear resistance and smoothness, particularly when coated with silicone surface paint, which results in a low coefficient of friction, facilitating the sliding of door and window sashes. Suitable for windows and doors with sliding panels. It serves as a substitute for the traditional siliconized flocking strips.
In recent years, the rubber industry has seen rapid development of new technologies, with quick product upgrades, especially in the field of fine rubber products outside of tires, which are advancing at an even faster pace. There is an increasing demand for rubber products, which are moving towards functionalization. New concepts are continuously emerging in product structure design. Tires are continuing to evolve towards flatness, miniaturization, and tubeless designs, while also boasting features like low noise, safety, comfort, and all-weather performance. In terms of hoses, there is a special requirement to extend the insurance period to over 10 years, and also for low permeability. The global demand for footwear is approximately 8 billion pairs per year, with a requirement for comfort, hygiene, and aesthetics.
