Target material / backup material round rod polyethylene foam
Excellent airtightness, elasticity, and cushioning properties, making it ideal for joint materials and sealant backup materials.
High-foam polyethylene foam molded into a round rod shape 【Features】 ■ Stabilizes the function of sealants Its round rod shape disperses internal stress in the sealant, prolonging its lifespan. Made of polyethylene, it does not adhere to sealants, achieving ideal two-sided adhesion. ■ Backup effect Maintains the shape of the sealant and prevents delamination of the adhesive surface due to stress concentration. ■ Moderate cushioning Withstands external pressure from the expansion and contraction of joints and is easy to install. ■ Does not absorb water Being made of closed-cell foam, it has minimal water absorption and moisture retention. ■ Durable and long-lasting, resistant to chemicals Can be used semi-permanently unless exposed to direct UV rays. No dissolution or deformation from solvents or primer liquids. □ For other functions and details, please contact us.
