Which items should pressure sensitive glue be tested?

Pressure sensitive adhesive is a kind of adhesive which is sensitive to pressure. Pressure sensitive adhesive can be divided into rubber type and resin type according to the main resin composition. It has been widely used in industry.

So what do you know about pressure sensitive adhesives? Do you know what items and standards need to be tested for pressure sensitive adhesive? Today, Xiaobian will take you to understand:

Test items:

Analysis items: formula analysis, composition identification, content analysis, composition comparison, etc.

Performance test: PH value, appearance, density, viscosity, viscosity, tensile strength, shear strength, peel strength, impact strength, softening point, bonding point, dielectric strength, dielectric constant, volume resistance, monomer content and other test items.

Environmental protection detection: methanol, heavy metals, benzene, toluene, free formaldehyde, chlorinated hydrocarbons, starch substances, ash substances, non-volatile matter content detection items.

Reliable performance testing: creep, fatigue strength, impact resistance, durability, aging performance, salt spray test and other testing items.
