DNA MISC Products
A comprehensive line of high-performance closed-cell foam tapes providing superior sealing against air, dust, and moisture in diverse applications.
EVA FOAM Tape
Resilient, closed-cell foam known for excellent flexibility, UV resistance, and quick recovery from compression. Great substitute for rubber materials.
Material Overview & Fabrication
EVA foam is closed-cell ethylene-vinyl acetate copolymer foam, processed via foam slitting. It retains strong resistance and flexibility, recovering quickly from compressions.
Key Properties & Advantages
Provides strong gloss/clarity, remains strong in low temperatures, and is highly resistant to UV radiation and stress cracking. It is very effective at absorbing vibrations and is resistant to weather, chemicals, fuel spill, and oil.
PE FOAM Tape
A durable and tough closed-cell Polyethylene foam tape combined with PSA adhesive backing for high utility indoor and outdoor tasks.
Material Overview & Durability
PE foam is a tough, resilient, closed-cell form suitable for commercial and industrial use. Its combination with PSA adhesive allows easy bonding to various surfaces.
Key Properties & Advantages
Known for its long life-span and integrity maintenance. A key feature is that Polyethylene foam sealing tape is flame retardant, offering resistance to fire and preventing rapid flame spread.
NITRILE FOAM Tape
A high-quality, practically indestructible blend of closed-cell rubber and plastic (vinyl nitrile). Offers unbeatable sealing and durability.
Material Overview & Use
A good alternative for latex, Nitrile foam is designed for superior durability, strength, and reliability. It is manufactured by forming gas bubbles in a plastic mixture.
Key Properties & Advantages
Features impressive waterproof properties, commonly used to keep pipes dry and prevent corrosion. Excellent for sealing in industrial settings, keeping out air, dust, and light moisture. Also useful for bonding metal surfaces.
EPDM FOAM Tape
Best for **weatherproofing** due to superior resistance to ozone, oxidation, and UV. Highly durable and cost-effective, meeting FMVSS 302 flame standards.
Material Overview & Temperature
EPDM is a closed-cell foam offering excellent heat resistance from $-40^\circ C$ to $105^\circ C$. Works as an electrolysis barrier and is ideal for NVH (Noise, Vibration, Harshness) solutions.
Key Properties & Applications
Most cost-effective choice for automotive and mass transit. Provides strong adhesive for positioning and is widely used for sealing doors and windows in buildings due to its durability and UV resistance.
NEOPRENE FOAM Tape
Provides the best resistance from weathering, ozone, and petrochemicals. Highly recommended for transport applications due to its resilience to oil and fuel.
Material Overview & Resistance
Neoprene is a pliable, rubber-like material with high insulating properties and chemical stability. It withstands temperatures between $-15^\circ C$ and $+105^\circ C$ and is FMVSS 302 flame retardant.
Key Properties & Applications
Its high resistance to petrol and oil makes it ideal for transport sealing in trucks, boats, and vehicles. It is impermeable to water and air, providing a premium seal for box and enclosure seals.
