Apple Rubber Offers Electrical Enclosure UL 50 Seals

By Editor | September 16, 2013

Apple Rubber Products now offers two new silicone compounds with UL 50 and UL 50E certifications for use with and without environmental considerations.

UL 50 and UL 50E are the safety standards for seal use with enclosures for electrical equipment, and Apple Rubber has selected two silicone compounds, 14SL7ML and 35SL5ML, to provide to customers who require products with these certifications. These compounds provide an ultra-low compression set, even at elevated temperatures, and offer the quality and durability customers need for safe operations.

Included in the UL 50 and UL 50E listings are end uses for atmospheric ozone and generated ozone, therefore eliminating any environmental concerns due to ozone attacks. These compounds don’t contain any phthalate plasticizers, which would craze plastic-based enclosures, or require any anti-corrosion inhibitors for metal enclosures. They are also cured without sulfur or peroxide to allow very little residue that may outgas and corrode electrical components.

Additionally, Apple Rubber has tested 14SL7ML to ASTM E 595, which is the standard for outgas testing. The results fell well within the screening levels for spacecraft materials which are less than 1% total mass loss (TML) and less than 0.1% collected volatile condensable materials (CVCM). The results for 35SL5ML were a TML of 0.33% and 0.05% CVCM.

These compounds also provide one of the largest temperature ranges, allowing for use in environments where temperatures are between -65°C and +200°C. Also, to provide even more flexibility for design engineers, these compounds have been approved for Type 12, 12K or 13 enclosures which require oil swell resistance.

With years of design and molding experience, Apple Rubber can provide the most complex configurations to meet almost any design requirements. The full service team at Apple Rubber is located in Lancaster, NY and is committed to helping customers design seals that meet UL 50, UL 50E and other certification standards.
