Description
Product Overview
Introducing the USA Sealing Acetal Plastic Bar, a 12‑inch long, 1½‑inch wide, and ½‑inch thick bar crafted from high‑quality acetal copolymer. This standard‑grade, black, opaque bar offers a Rockwell M90 hardness and a tensile strength of 9,100 psi, making it ideal for demanding industrial applications. With a low coefficient of friction (0.35) and excellent water resistance (0.0022 % absorption), it performs reliably from –50°F to 180°F and meets UL 94 HB flame‑retardant standards.

FAQ
What machining methods are suitable for this acetal bar?
The bar can be machined using standard CNC milling, turning, and drilling tools. Use sharp carbide bits to achieve clean cuts and maintain surface finish.
Is the material suitable for food‑contact applications?
While the bar meets many industrial standards, it is not certified for direct food contact. For food‑grade needs, select a material specifically rated for FDA compliance.
Can the bar be glued or bonded?
Yes, acetal bonds well with solvent‑based adhesives designed for plastics. Follow the adhesive manufacturer’s instructions for best results.
What is the recommended storage condition?
Store in a dry, temperature‑controlled environment away from direct sunlight. Maintaining temperatures between –20°F and 200°F preserves material integrity.
How do I verify the UL94 HB rating?
The UL94 HB rating is documented in the product certification sheet provided with each order. Contact our support team for a copy if needed.
