Double-sided acrylic adhesive tape has a durable bond, high strength, and performs well over a wide temperature range, providing a long-lasting alternative solution for mechanical welding and other bonding methods.
Challenges of LSE Plastics
Low surface energy (LSE) plastics, or commonly known as LSE plastics, include materials such as polypropylene (PP), polyethylene (PE or HDPE), polystyrene, acetal, EVA (ethylene vinyl acetate), and coated paints.
In general, these plastic materials have low melting temperatures, making them easy to process, even in large quantities, and have low density, resulting in lightweight. Because low surface energy is a key characteristic of this plastic group, they are more difficult to bond, requiring specialized solutions such as low surface energy plastic adhesive tape.
Low surface energy (LSE) presents a challenge because the necessary plastic-to-plastic bond lacks adhesion and requires additional primers, which are costly, time-consuming, have unpleasant odors, and involve numerous other steps in the process. These challenges may hinder the bonding of synthetic materials and LSE plastics and ultimately alter the creative design process.
Polypropylene
Polypropylene is a low-density plastic produced in very large quantities and widely used as films, fibers, and molded parts. It is commonly used for packaging as containers, absorbent pads, and wrapping films, as well as to create lightweight components for automotive, equipment, and medical industries.
Polystyrene
Polystyrene is a rigid, transparent plastic; brittle, but stiffer versions called high-impact polystyrene (HIPS) have different bonding properties. Polystyrene is easily processed by molding, allowing for the creation of intricate details, as well as by vacuum forming to produce foam sheets.
Polyethylene
Polyethylene is the most common plastic, produced in the largest quantities, often made into wrapping films for packaging, bottling, or other containers. Polyethylene has relatively low strength, poor heat resistance, but is easy to process and is used for applications where these factors are less critical.
Acetal/Polyoxymethylene/POM
Polyoxymethylene is a high-performance opaque white plastic with high strength, stiffness, impact resistance, and good temperature resistance. It is often used in parts such as gears, conveyor belts, frames, cable ties, etc.
EVA
Ethylene vinyl acetate is a rubber-like polymer, with good flexibility and crack resistance. It is often used as foam in footwear, especially as midsoles for sneakers and tennis shoes, and sports padding; it can also replace natural cork stoppers.
Paint and Powder Coating
Traditional paint types have various surface energy types leading to different bonding requirements.
Adhesive Solutions for Hard-to-Bond Plastics
LSE tape is a quick, easy, and reliable bonding solution for low surface energy (LSE) substrates. In addition to the plastics mentioned above, the tape also bonds to: thermoplastic olefins (TPO) and thermoplastic elastomers (TPE), composite materials such as glass-reinforced plastic (GRP) or fiber-reinforced plastic (FRP).
Specialized tape for low surface energy plastics is double-sided foam acrylic tape, creating a long-lasting bond, with high durability and performance across a wide temperature range. It offers a durable alternative to welding and traditional mechanical bonding methods.
Advantages:
- Bonding without the need for primer on difficult substrates.
- Increased speed and productivity.
- Reduced use of chemicals, making it safer.
- Provides long-term outdoor durability.
- Offers more design flexibility.
- Reduces manufacturing costs.
Tape for low surface energy provides high initial adhesion at low temperatures, allowing manufacturers to benefit from faster and more reliable bonds in normal environments, such as outdoor applications or factory floors. This low temperature capability enables immediate handling strength in various environments, eliminating wait times for assembly to continue in the manufacturing process.
