（1） Physical and chemical index detection

We can provide physical and chemical indicator testing services for CMA certification institutions, high-tech enterprises, third-party material laboratories, with complete instruments and a strong research team. We can issue testing reports within 7-15 working days, support scanning code to check authenticity, and provide on-site sampling and sample sending testing services nationwide. Our testing cycle is short, the testing cost is low, and the testing data is scientific and accurate! Testing cycle: 7-15 working days Testing cost: Engineers will develop experimental plans based on customer testing needs and experimental complexity for quotation. The detection range of physical and chemical indicators includes metal minerals, polymer materials, packaging materials, plastic and plastic products, food contact materials, petrochemicals, soil water quality, additives and other fine chemicals, toys and children's products, automotive materials and components, clothing/bags/shoes, etc. Physical and chemical indicators testing items Physical indicators: specific gravity test, apparent density, yellow index, whiteness, swelling ratio, water content, acid value, hardness, plastic linear expansion coefficient, density, relative density test, water absorption, ash content measurement, transmittance, permeability, haze, Ph value, color, odor, state, gray card rating, conductivity, thermal conductivity, ductility, solubility, viscosity, particle size, melting point, boiling point, solidification point Ignition point, flash point, thermal conductivity, electrical conductivity, magnetic properties, elastic modulus, coefficient of thermal expansion, specific heat capacity, thermal stability, volatility, adsorption, sound insulation, etc. Mechanical indicators: hardness, tensile performance, bending performance, impact performance, compression performance, compression permanent deformation, tear performance, peel strength, adhesive strength, shear strength, rebound performance, wear resistance, friction coefficient, brittle temperature, temperature test, humidity test, low-temperature shrinkage (TR test), collision test, drop test, rolling performance, vibration test, fatigue resistance, pulse test, high-speed performance, durability Low pressure performance, burst pressure, hydrostatic testing, resistance to environmental stress cracking, etc. Rn -- -- -- -- -- rn Copyright Notice: This article is an original article by Beijing Zhongke Light Analysis Chemical Technology Research Institute, with copyright agreement.
