Sealing strips play a crucial role in building construction as they prevent air, water, and dust from entering the building. Traditionally, sealing strips were made using materials such as PVC, neoprene, and EPDM. However, TPE (Thermoplastic Elastomer) material has emerged as a better alternative for building seals due to its numerous advantages over ordinary sealing strip materials.
TPE is a blend of rubber and plastic polymers that provide excellent sealing properties as well as durability. TPE materials are available in a variety of grades, each with specific features and properties. Here are some of the key advantages of TPE material for building seals:
1. Superior sealing properties: TPE material has a great ability to form a tight seal around doors and windows. It has high elasticity and can stretch to fit any shape. TPE seals compress easily and return to their original shape without losing their sealing effectiveness. This property ensures a long service life for TPE seals.
2. Weather-resistant: TPE material has good weather resistance and can withstand a wide range of temperatures. Unlike PVC or neoprene, TPE seals do not become brittle in cold temperatures, making them ideal for use in regions with high temperature fluctuations.
3. Environmentally-friendly: TPE material is a green material as it is recyclable. It does not contain any hazardous chemicals, so there is no risk of environmental pollution during use or disposal. TPE material can be used in applications where sustainability is a priority.
4. Excellent UV resistance: TPE material has excellent UV resistance and does not degrade when exposed to sunlight. This property is especially important for outdoor applications where the sealing strip is exposed to direct sunlight for extended periods.
5. Easy processing: TPE material is compatible with most extrusion equipment, making it easy to produce sealing strips with varying shapes and sizes. TPE material is easy to color, and a variety of colors are available.
Dawn Polymer offers two typical TPE grades for building seals – TPE 6512-PB and TPE 5811-PB. TPE 6512-PB and TPE 5811-PB have good balance of hardness and flexibility, making them ideal for use in sealing strips.
TPE material is the ideal choice for building seals due to its superior sealing properties, excellent weather and UV resistance, and environmentally-friendly nature. With the variety of grades available, TPE material meets the requirements of different applications and ensures that building seals function optimally.
