HDPE is resistant to many different solvents, and is exceptionally challenging to glue; joints are typically made by welding. The physical properties of HDPE can vary depending on the molding process that is used to manufacture a specific sample; to some degree, a determining factor is the international standardized testing methods employed to ...
Solvent bonding – Adhesives and solvents are rarely used as solvent bonding because polyethylene is nonpolar and has a high resistance to solvents. Pressure-sensitive adhesives (PSA) are feasible if the surface chemistry or charge is modified with plasma activation , flame treatment , or corona treatment .
The strain hardening modulus when measured at 80 °C is sensitive to the same molecular factors that govern slow crack resistance in HDPE as measured by an accelerated ESCR test where a surface active agent is used. [9] The strain hardening modulus and ESCR values for polyethylene have been found to be strongly correlated with each others.
Higher molecular weight of the polymer chains provides higher tensile strength and heat resistance. Presence of unsaturated bonds makes the adhesive more susceptible to autoxidation and UV degradation and necessitates use of antioxidants and stabilizers. The adhesives are usually clear or translucent, colorless, straw-colored, tan, or amber.

The material has good clarity and gloss, low-temperature toughness, stress-crack resistance, hot-melt adhesive waterproof properties, and resistance to UV radiation. EVA has a distinctive vinegar-like odor and is competitive with rubber and vinyl polymer products in many electrical applications.
