Chloroprene CR Rubber Diaphragm Seals Neoprene Gasket Seal Ozone resistance Weather Resistance Aging resistance

Introduction:

Hongum specializes in precision die cut and molded neoprene rubber gaskets and seals for a wide range of industries and applications worldwide. Neoprene is an extremely versatile synthetic black rubber used for harsh environment applications due to its excellent resistance to oil and petroleum base solvents. Neoprene resists deprivation from sun, ozone and other weather elements. It also displays incredible resistance to damage caused by flexing and twisting. Another advantage of neoprene rubber is that it has very good resistance to dilute acids, alkalis, oils, greases and solvents. Neoprene has the ability to work well in temperatures ranging from -40°F to +230°F, intermittent to +250°F. Neoprene gaskets are used for equipment in all industries.

Neoprene Gasket (CR Rubber Gasket)

Neoprene gaskets have good ozone resistance, weather resistance and aging resistance. At the same time, it also has good flame retardancy, mechanical properties and cold resistance. The operating temperature range of chloroprene rubber is -40°C~+100°C (up to +120°C in a short time). Special types of chloroprene rubber can work as low as -55°C. Neoprene gaskets are often used in 1. Precision machinery, medical equipment, furniture, glass, electrical appliances and other transportation buffer materials; 2. Doors and windows, pipes, lamps, instrument sealing materials, sound insulation of mechanical equipment, residential sound insulation wall sealing materials ; 3. anti-shrinkage gasket materials; 4. laptop computers, electronics, electrical appliances and mechanical equipment waterproof and moisture-proof sealing materials.

Features and Benefits of Neoprene Gasket Products:

1) Good tear strength;
2) It has an independent cell structure and low water absorption;
3) It has moderate elasticity and can be used as a buffer material;
4) Good fire resistance.

National standard, Japanese standard, American standard, European standard and other standard thicknesses of 1.5mm and 3mm can be provided. Other thicknesses of 3-50mm can be customized.

Die Cut Neoprene Gaskets

Hongum provides die cut neoprene rubber gaskets in a wide variety of grades, thicknesses and hardness. The standard thickness of neoprene rubber ranges from 1/64″ to 3/8″ thick. Die cut neoprene gaskets are typically black in color and their hardness (durometer) spans from 30 to 90 durometer, Shore A. Neoprene gaskets are available with or without pressure sensitive adhesive (PSA) backing.

Adding Pressure Sensitive Adhesive (PSA) Backing

Most of the materials listed above are available with or without a pressure-sensitive adhesive (PSA) backing, depending on the needs of the customers. While the addition of a PSA backing reduces the amount of time and labor required for the installation of a gasket, it is not recommended for the following applications:

• When using EMI shielding gaskets (the adhesive can reduce the effectiveness of the shielding material)

• When solvent resistance is critical (the adhesive is susceptible to degradation and damage from solvents)

• When there is little flat surface area (the adhesive cannot form an adequate adhesive bond without sufficient surface area)

• When the gasket will be subjected to regular stress (the adhesive may lose its integrity over time)

Key Selection Considerations for Gasket Materials

When choosing a gasket material, there are several factors to keep in mind to ensure the one chosen is appropriate for the intended application. Some of the key considerations are:
