Different Uses of TPU Hot Melt Adhesive Granules
TPU (thermoplastic polyurethane) is a hot melt adhesive granule that can be used in various applications, such as crafting and industrial bonding. It has excellent adhesion capabilities, making it the ideal choice for a wide range of different projects. Here are some of the common uses of TPU hot melt adhesive granules:
# Crafting
TPU hot melt adhesive granules can adhere to different materials in craft projects. The robust and durable bond makes it an ideal choice for art/craft projects where other types of glue don’t have the same strength and durability.
# Industrial Bonding
TPU hot melt adhesive granules are also great for industrial bonding applications. Due to its superior adhesion properties and low melting temperature, it is suitable for many industrial bonding processes.
# Painting
TPU hot melt adhesive granules can be a sealant when painting surfaces or crafts such as woodworking projects. Sealing the surface with the granules prevents any unwanted paint from seeping into any cracks or joints in the surface material, creating a seamless and smooth finish every time.
# Packaging
TPU hot melt adhesive granules can be used as a sealant when packaging products such as food or pharmaceuticals to prevent moisture from entering and spoiling the product inside.
# Automotive Repairs
TPU hot melt adhesive granules can also be used in automotive repair jobs to attach parts that need strong adhesion properties, such as car door handles, mirrors, bumpers and more.
Ways to Store and Handle TPU Hot Melt Adhesive Granules Properly
Storing and properly handling TPU hot melt adhesive granules is essential for proper adhesion and longevity. Here are a few tips on how to do it right:
- Use an airtight container or bag to store the granules when not in use. This will help prevent them from drying out.
- Wear protective gear such as gloves or a face mask while handling the granules, as they can be irritating if inhaled.
- Do not exceed the recommended temperature range of 180°F (82°C) when using the TPU hot melt adhesive. Excess heat can cause the granules to degrade quickly.
- Keep the granules away from moisture, and direct sunlight, as this can also cause them to break down over time.
- Ensure that you are stirring the mixture well during the application, as any clumps may not adhere properly and create an uneven finish.
