Description
Wholesale Direct Selling High Density Sponge EVA Foam Display Protective Foam Packing Foam
EVA foam is a copolymer made from ethylene and VA foam.
The general VA eva content is 5% to 40%. Compared with polyethylene, EVA material is due to the introduction of VA monomer in the molecular chain. Thus reduce the crystallinity, improve the flexibility, impact resistance, filler phase solubility and thermal sealing performance, is widely used in foam shoe material, functional shed film, packaging film, hot melt adhesive, wire and cable and toys and other fields.
1.Good cushioning and seismic performance
2.Heat insulation, moisture, chemical corrosion resistance
3.Easy to process (hot pressing, cutting, etc.)
4.Meet ROHS, etc
Product Application:
Toys, electronic appliances, stationery office
Hardware, furniture, sports equipment protection
Thermal insulation, tourism, decoration, crafts
Jewelry, cosmetics, environmental protection packaging, etc

<<<<<< Chemistry Lab
·Researsh and development of polymer structure
·Study on modification of silicates and dispersion of nanoparticles
·Study on synthesis of composite materials
Whenever we need to make samples or make a large order, we will first go through the chemical laboratory to prepare and reproduce.
Chemistry laboratories can be used to research and test the feasibility of product development solutions. It can also be used as a research studio to help researchers explore and master the progress of product development.
It is helpful to determine the stability of product performance and lay the foundation for the successful completion of orders.
Physical Lab >>>>>>
·The pgysical and electrical properties of the product were teste and studied
·The combination performance of modul products is tested and studied
·Analog client-side application testing
When our product formulation is determined, it is necessary to test whether the product performance meets the standard. Our physical tests include: viscosity test, tensile test, stickiness test, resistance numerical test and so on.
Experiments in the laboratory can help us measure and collect data, and data can be analyzed using measuring instruments in the physics laboratory to verify and prove theoretical knowledge.
The collected data can be integrated together to get a specific product attribute table, which is more convenient for customers to quickly correspond to their own products.
<<<<<< Aging Lab
·Provide the conditions for the normal use of the product
·Provides the use condition of the product under the extreme enviroment
·Provide the necessary conditions for product reliability
In order to simulate the service life of products, we carry out "extreme environment" product aging experiments, mainly ultra-low temperature, constant temperature, ultra-high temperature environment.
The product will be placed in the equipment to bake for a period of time, and when it is taken out, there is no dry cracking, debris falling, thermal conductivity change rate less than 20%, hardness change less than 10%, etc., it is considered to be up to standard.
