Structural formula:
Use:
B564 is a ternary * * * poly resin. It is a product carefully developed by Japan Liyuan Company to improve the toughness of PVC by adopting the most advanced synthetic resin technology.
When B564 is added to PVC formula, the toughness of the product is obviously improved, but the inherent characteristics of PVC, such as thermal stability and processability, are not adversely affected. B564 is powder, which is suitable for dry mixing with PVC. The mixture can be made into various hard, semi-hard and soft products, such as granules, films, sheets, plates, profiles, pipes and bottles, by processes such as blow molding, calendering, extrusion and injection molding.
B-564 is specially used to improve the toughness of PVC opaque products. It is the best product for Zhongyuan Company to improve toughness. It is suitable for PVC products that require high toughness but low transparency, focusing on solving the toughness problem in PVC pipes, PVC pipe fittings and PVC profiles. It is a special toughening resin for PVC injection molding, and has good injection dispersibility in the field of high temperature and low shear. It greatly improves the toughness, especially in the field of hard failure, but it is generally resistant to low temperature. It has the characteristics of high toughness and small addition (70% of domestic products).
Product features:
1.B564 is a terpolymer of methyl methacrylate, butadiene and styrene, and it is the best toughening material for PVC products.
2. Excellent compatibility with PVC, thus ensuring its uniform dispersion in PVC and excellent processability.
3. Excellent surface smoothness and rigidity retention. 4. The particle size is uniform and is not affected by the mixing process. 5. There is no migration and no frosting.
6. Odorless, which has no effect on the original smell of the resin.
7. Non-flammable, non-explosive, non-toxic, non-corrosive, non-dangerous, safe to use and safe to operate. Many countries allow this product to be used in plastic products that come into contact with food.
Zhongyuan company's products are the most famous and excellent toughening agent in the world, which combines all kinds of excellent properties.
Suggested dosage in PVC: (Note: The more plasticizer in the formula, the less dosage of toughening agent; The thicker the product, the greater the dosage of toughening agent. )
Rigid PVC products: 3- 10%
Semi-rigid PVC products: 2-8%
Soft PVC products: 1-5%
Before use, a small experiment should be conducted to determine the final formula. The data added above is for reference only. Enterprises should reduce or increase the above reference dosage according to the different formulas, uses and properties of their products, so as to achieve the best use effect.
Special instructions:
1. Because B564 contains butadiene with unsaturated structure, it is easy to age under the action of oxygen and ultraviolet rays, so the weather resistance is slightly poor, so it should be verified to be used to make products for long-term outdoor use.
2. Try not to touch the liquid when using, so as to avoid the expansion of B564 due to absorbing the liquid, resulting in rough surface and poor transparency. The specific method is: firstly, mix PVC powder with all liquid raw materials, and then mix with B564 after the liquid raw materials are absorbed by PVC.
Packing: Three-layer kraft paper bag with net weight of 20kg/bag.
Storage and transportation: generally stable, stored in a dry and cool place, but after the package is opened, it needs to be sealed in time or used as soon as possible. Store and transport according to non-dangerous goods.
