(-40+160) and other excellent performance, has been widely used in automotive doors and windows and other manufacturing industries. For different shapes, different materials, or cold-resistant, heat-resistant, foaming, solid body, and products with special performance requirements, can meet the design and use requirements.
Features: Using EPDM as raw material, the surface is smooth and detailed, good resilience, good bubble uniformity, first-class waterproof performance, ozone resistance, aging resistance, and good solvent resistance. EPDM/Rubber/Foam Products:
EPDM sealing strip has excellent weathering resistance and weather resistance, which means it has long-term resistance to cold, hot, dry and wet, and it has excellent corrosion resistance to snow and snow erosion, and can fully extend the strip.
The service life of the heat aging resistance means that there is a strong resistance to air aging. Can be used at 100-120°C for a long time, and can remain effective for a long period at 140-150°C
The physical properties can withstand high temperatures of 230-260°C in a short time, and can have a time-delay effect on unexpected accidents in urban buildings. With the use of special formula, EPDM rubber is at -50°C.
Similar to 150°C, which creates an efficient job performance for production site installation
Due to the excellent ozone resistance of door and window seals, it is also known as “cracks free rubberâ€, especially applied to various urban buildings with different atmospheric indexes and completely exposed to the air.
The EPDM rubber was selected as the rubber material for the brake cup because 1) EPDM rubber is very resistant to polar PEG brake fluid. 2) Due to the increase of the vehicle speed and frequent braking, the brake fluid temperature increases due to high friction, and the local temperature can reach 150°C. The good water resistance of EPDM rubber and good dynamic performance and weather resistance at high temperatures make it EPDM rubber becomes the main rubber type for brake cups. Fourth, the dust cover includes a universal joint dust cover and a rack rod dust cover. The types of rubber used by the manufacturers vary. Thermoplastic EPDM and thermoplastic TPV and CR are commonly used. Although the dust cover is simple, it also requires heat resistance, cold resistance, oil resistance, fatigue resistance, ozone aging and tensile properties. CR (chloroprene rubber) can be used with good cold resistance, it should be an ideal dust cover rubber species. Because it takes into account oil resistance. In the market today, dust caps made of thermoplastic EPDM and dust caps made of TPV (thermoplastic polyurethane elastomer) are available.
Thermally Inactive Reflective Liner material is a 3layer co-ertruded Geomembrane. The product core and inferior layer remain black which doesn`t affect any technical properties of the liner. By changing the composition of the superior layer the addition of a pure white pigment composed of UV additives, Tianhai created a product that offers additional on-site benefits suitable for various applications.
Features:
Geomembranes were created to contain solids and fluids for very long periods. As such, they need to have high endurance properties. One of the best additives for plastics to resist to UV degradation is carbon black. However, this results in having black geomembrane. Black geomembrane will get very hot when exposed to sunlight because of its high expansion/contraction coefficient.
Tianhai innovated in developing a new reflective geomembrane. While having obvious aesthetic advantages, the reflective liner will also reflect the sunlight and reduce the temperature of the geomembrane. This reduction in temperature will reduce the expansion/contraction of the geomembrane which will allow for an easier installation and reduce wrinkles in the liner. For composite liner systems, reducing the wrinkles will increase the intimate contact between the liner and the low permeability sub layer which will lead to a more efficient impermeable system. It will also slow down the aging process and increase its service life.
Another advantage of the reflective geomembrane is the contrast between the white surface layer and the black core of the liner. This allows easy identification of visual defects as they will be more apparent than on traditional black geomembranes.
While reflective geomembranes seem to only offer aesthetical advantages, as expressed above, significant benefits result from using reflective geomembrane over traditional black geomembrane.
