At R4 Gaskets, we specialise in manufacturing high-quality polyethylene foam gaskets from cross-linked, closed-cell material. These gaskets are perfect for a wide range of standard and everyday applications. In addition to standard polyethylene, we offer Plastazote® and Evazote® grades, providing a variety of thicknesses and densities to meet your specific needs.
Superior Chemical Resistance
Our polyethylene foam gaskets are renowned for their excellent chemical resistance. They effectively withstand exposure to acetatic acid, ammonium hydroxide, calcium hydroxide, diethylene glycol, ethylene glycol, ethanol, glycerin, glycol, hydrogen peroxide, mercury, methanol, potassium hydroxide, and sodium hydroxide. This ensures stability and durability, even in the most abrasive environments.
Water Repellence and Weather Resistance
As a closed-cell material, our polyethylene foam gaskets are naturally water repellent, enhancing their buoyancy and making them impervious to mildew and bacteria. Additionally, these gaskets offer robust resistance to weather and UV deterioration, making them ideal for exterior sealing applications.
Plastazote® & Evazote® Gaskets
Which Material is Right for You?
Plastazote® and Evazote® gaskets are produced using a unique nitrogen expansion process, resulting in gaskets with higher purity, consistent densities, and controlled cell sizes. This process also allows for enhancements like superior flame retardance and high-temperature resistance. Below, we outline the key differences between Plastazote® and Evazote® gaskets.
Plastazote®
Plastazote® gaskets are known for their excellent mechanical properties, including impact absorption, compression recovery, high strength, and durability. They provide exceptional resistance to most oils, solvents, acids, and alkalis, making them suitable for automotive and construction applications. Plastazote® is also lightweight and free from chemical agents, making it popular in scientific and medical industries.
Evazote®
Evazote® gaskets offer superior softness, durability, and resilience compared to Plastazote®. They can absorb various impacts and pressures without warping or deteriorating and have increased resistance to many abrasive chemicals. This makes Evazote® ideal for use in harsh and intense environments.
