Adhesive manufacturers share that the main performance indicators of epoxy resin are 123
Adhesive manufacturersThe physical properties of epoxy resin refer to its density, water absorption, melting point, and other characteristics. Density is an important physical property indicator of epoxy resin, which directly affects the quality and cost of the material. Water absorption is the ability of epoxy resin to absorb water in humid environments, and for some applications that require use in humid environments, water absorption is a key indicator. The melting point is the temperature at which epoxy resin melts during heating, which is of great significance for the processing and molding of epoxy resin.
Epoxy value:
The amount of cyclic hydrogen substances contained in every 100 grams of epoxy resin. Epoxy group content: The mass of epoxy groups contained in every 100 grams of epoxy resin. Epoxy equivalent: The mass of epoxy resin containing one epoxy group, multiplied by the reciprocal of the ring value by 100.
Viscosity:
Viscosity is a mandatory property of low molecular weight epoxy resin and an important indicator related to the adhesive application process. Use Tu-4 viscometer (4mm aperture), Tu-1 viscometer, rotational viscometer, etc.
Softening point:
It is an important performance indicator of epoxy resin and a necessary property for measuring medium molecular weight.
Volatile matter:
100g resin contains low molecular impurities and volatile components.
The main performance indicators of epoxy resin cover multiple aspects such as physical properties, mechanical properties, thermal properties, and electrical properties, which are of great significance for material selection and design. In practical applications, we need to choose the appropriate epoxy resin based on specific needs and environmental conditions to ensure that the material has good performance and reliability.
