Pressure-Sensitive Adhesive (PSA) is an adhesive that bonds to substrates upon application of light pressure, without the need for water, solvents, or heat. Its characteristics include permanent tack, peelability, and good adhesion to various surfaces (such as paper, plastic, metal). In foreign trade, PSA is commonly used in products like tapes, labels, protective films, and medical dressings, making it an important category in the adhesive industry. Usage scenarios include export tapes, label paper, automotive films, etc. Note: Specifications such as the PSA's base material (e.g., acrylic, rubber), initial tack, holding power, and temperature resistance must be clearly specified to avoid confusion with hot melt adhesives or solvent-based adhesives. Difference: PSA bonds by pressure, while hot melt adhesives require heating to melt, and solvent-based adhesives require solvent evaporation. Foreign trade contracts should specify adhesive parameters, test standards (e.g., ASTM D3330), and environmental requirements (e.g., RoHS).
📝 Examples
1. Our exported BOPP carton sealing tape uses water-based acrylic pressure-sensitive adhesive, with initial tack ≥18# steel ball and holding power >24 hours, compliant with EU RoHS directive. (Note: Specify PSA type and key performance indicators for contracts or product descriptions.)
2. Please confirm whether your pressure-sensitive adhesive labels' peel force meets 1.0-1.5 N/25mm, so we can arrange sea shipment to Hamburg Port. (Note: In inquiries or order confirmations, use PSA terminology to communicate technical parameters and logistics arrangements.)
💡 Foreign Trade Tips
Foreign trade terms are the foundation of international business communication
Trade practices may vary slightly by country; pay attention when using them
When using terms in contracts, specify the applicable version (e.g., Incoterms 2020)
