109-48-8 Usage
Chemical composition
The copolymer is formed by polymerizing 1,2-Benzenedicarboxylic acid di-2-propenyl ester with ethyl 2-propenoate and 2-methyl-2-propenoic acid.
Category
Thermoplastic polymer.
Applications
Widely used in the production of flexible and durable products such as packaging materials, adhesives, wire and cable insulation, and footwear.
Flexibility
The copolymer has excellent flexibility due to the presence of ethylene and vinyl acetate units in its structure.
Impact resistance
The material is known for its ability to absorb and dissipate impact energy, making it suitable for various applications.
Weatherability
The copolymer exhibits good resistance to UV radiation and other environmental factors, ensuring its durability in outdoor applications.
Non-toxicity
EVA copolymer is considered non-toxic and safe for use in various applications, including those that come into contact with food or human skin.
Molecular structure
The copolymer consists of a long chain of repeating units, with the ethylene and vinyl acetate units alternating along the chain. The presence of these different units contributes to the material's unique properties.
Manufacturing process
EVA copolymers are typically produced through a process called high-pressure polymerization, which involves mixing the monomers under high pressure and temperature to initiate the polymerization reaction.
Recycling
EVA copolymers can be recycled, and their recycling code is generally marked as "2" or "4" depending on the specific formulation and application. Recycling helps reduce waste and conserve resources.
Check Digit Verification of cas no
The CAS Registry Mumber 109-48-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,0 and 9 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 109-48:
(5*1)+(4*0)+(3*9)+(2*4)+(1*8)=48
48 % 10 = 8
So 109-48-8 is a valid CAS Registry Number.
