Ethylene Vinyl Acetate an overview ScienceDirect Topics
Ethylene vinyl acetate (EVA) is the most common polymer used in hot melt adhesives for packaging applications [19 ]. Vinyl acetate levels used in adhesives vary from 6 to 40%. The higher the vinyl acetate the softer and less crystalline the polymer. At about 50% vinyl acetate all crystallinity is lost (see Fig. 3 ).
Here we list the typical usage of antioxidant, UV stabilizer for adhesives and sealants. For Adhesives and sealants, hindered phenolic antioxidant 1010 or 1076 is suggested for processing and long-term stability. UV absorber p, light stabilizer 770 used individually or together to achieve a synergetic effect.
Vulcanization an overview ScienceDirect Topics
Nicholas P. Cheremisinoff Ph.D., in Condensed Encyclopedia of Polymer Engineering Terms, 2001 VULCANIZING AGENTS. Vulcanization is a chemical reaction between rubber and a functional group, usually brought about by heat. The result is a product that is stronger, more elastic, more resilient, and less sensitive to temperature changes and the action of solvents

Phosphites are most effective during processing and protect both the polymer and the primary antioxidant. Thioethers are useful in increasing the long-term thermal stability in conjunction with phenolic antioxidants. Irgafos ® 168, Irgafos ® 126, Irganox ® PS 800 and Irganox ® PS 802 are secondary antioxidants.

Phosphites are most effective during processing and protect both the polymer and the primary antioxidant. Hydrolytically stable phosphites are the most frequently used processing stabilizers in high-performance additive systems. Thioethers are useful only in increasing the long-term thermal stability in conjunction with phenolic antioxidants. The use of thioethers is limited to

- What is antioxidant 1076?
- Antioxidant 1076 is a non-staining, high molecular weight, hindered phenolic antioxidant. Because of its low volatility, Antioxidant 1076 imparts excellent heat stability and color retention, with good compatibility and low extractability. Ash Content . . . . . . . . . . . . . 0.1% max.
- What is Irganox 1076 used for?
- ApplicationsIrganox® 1076, a sterically hindered phenolic antioxidant, is a highly efficient, non-discoloring stabilizer for organic substrates such as plastics, synthetic fibers, elastomers, adhesives, waxes, o ls and fats. It protects these substrates against thermooxidative
- What is Veenox 1076 PW?
- Veenox 1076, a sterically hindered phenolic antioxidant, is a highly efficient, non-discolouring stabilizer for organic substrates such as plastics, synthetic fibres, elastomers and adhesives. It protects these substrates against thermal and oxidative degradation. Veenox 1076 PW is odourless, stable to light and has excellent colour retention.
- Which polymers are compatible with Veenox 1076?
- Compatibility with various Polymers: Veenox 1076 demonstrates excellent compatibility with a wide range of polymers, including polyolefins (polyethylene, polypropylene, polybutene-1), engineering plastics, styrene home and copolymers, polyurethanes, elastomers, and adhesives.
- What is Veenox 1010 & 1076?
- Veenox 1010 and Veenox 1076 go into Rubber applications. Veenox 1076 is preferred in HIPS & ABS due to its rubber content. The product is available in both PW (Powder) and GR (Granule) form. 25kg/Bag, 500kg/Pallet, 10MT/20’FCL.
- How many PPM can a polymer have?
- Dosage: Dosages can range from 500 to 2000 ppm, providing long-term thermal stability to polymers. Higher dosages up to 40000 ppm can be utilised depending on the specific substrate and desired level of thermal equilibrium.
