Detection Method Of Plastic Bottles

Detection Method Of Plastic Bottles

Plastic bottle testing items:

1. Routine detection: appearance, particle size, apparent density, density, water absorption, solid content, volatile content, etc.;

2. Chemical testing: toxic and harmful substance content, monomer residues, pH value, acid value, hydrolyzed acid value, hydroxyl value, cross-linking degree, chlorine content, etc.;

3. Mechanical performance test: tensile strength and elongation, tensile modulus of elasticity, flexural strength, flexural modulus of elasticity, compressive strength, Izod impact strength, simply supported beam impact strength, shear strength, tear strength, Peel strength, puncture performance, Shore hardness, Rockwell hardness, ball indentation hardness, drop impact, environmental stress cracking resistance, etc.;

4. Thermal performance test: melting point, oxidation induction time, melt flow rate, heat distortion temperature, Vicat softening temperature, linear expansion coefficient, oxygen index, thermal stability, softening point, etc.;

5. Electrical performance test: dielectric constant, dielectric loss factor, volume resistivity, surface resistivity, etc.;

6. Aging detection: xenon lamp aging, fluorescent UV lamp aging, thermal aging, etc.;

7. Other test methods: molding shrinkage, viscosity, light transmittance, chromaticity, haze, gel time, hydrolysis rate, carbon black content, etc.
