What kind of copolymer resin is BOVC resin?

I did a search: BOBV resin is a new type of PVC processing aid that is based on acrylates and synthesized through copolymerization with other monomers. It has a solubility parameter similar to that of PVC resin, resulting in excellent compatibility and blending properties. It can be widely used in the molding of rigid and flexible PVC products, boasts excellent performance, and is an upgraded version of ACR. It can improve the impact strength, low-temperature flexibility, surface gloss, and light and aging resistance of the product. Product performance: 1. It has good compatibility with PVC resin, disperses easily in PVC resin, and is easy to handle. 2. It possesses internal plasticity; when used in sole materials, wire and cable materials, as well as soft transparent materials, it reduces the amount of plasticizer required and addresses the issue of plasticizer migration to the surface. 3. It can significantly improve the low-temperature toughness and impact strength of the product. 4. Significantly improves the surface gloss of the product, outperforming ACR. 5. Good thermal stability and weather resistance. 6. Reduce melt viscosity, shorten plasticization time, and increase output per unit volume. Improve the impact strength and low-temperature toughness of the product. 7. Equimolar substitution of ACR allows for a reduction in the amount of lubricant used or an increase in the amount of filler used, while maintaining the material’s properties. This opens up new avenues for improving product quality and reducing costs. Several advantages of BOVC over ACR: 1. When BOVC is used in place of ACR in PVC, its plasticizing effect on PVC is better than that of ACR. 2. When BOVC is used in PVC flame-retardant insulated electrical sleeves, both the compressive strength and resilience of the resulting products are improved, addressing the problem of the products becoming soft in summer when ACR is used as a processing aid to manufacture flame-retardant electrical sleeves. 3. It produces products with the same visual appearance; the amount of BOVC used is less than that of ACR, its gloss level is higher than that of ACR, and the likelihood of pattern formation is much lower than with ACR. 4. During product extrusion molding, the current required when BOVC is added is lower than that for ACR, and its fluidity is also better than that of ACR. Save electricity and improve production efficiency. 5. When BOVC is used in extruding PVC pipes, it can reduce the amount of lubricant required. Application scope: 1. It is widely used in the processing of PVC profiles, sheets, pipes, transparent products, wire and cable materials, and shoe sole materials, and can completely replace ACR. 2. When used in combination with CPE, the amount of CPE required can be appropriately reduced. Physical and chemical properties of the product: Appearance: white powdery particles

It is a copolymer of small amounts of butyl acrylate, octyl acrylate, and VCM

So, is it random copolymerization or graft copolymerization? I believe that when butyl acrylate is randomly copolymerized with VCM, it merely serves to lower the glass transition temperature of PVC, enabling the products to exhibit elastomeric properties at room temperature. By first preparing an emulsion of PBA and PEHA (butyl acrylate, octyl acrylate), and then copolymerizing it with VCM, a dual effect is achieved: toughening and internal plasticization of PVC. Furthermore, is this copolymer an emulsion copolymer or a suspension copolymer? In the case of emulsion copolymerization, the resulting emulsion, after spray drying, yields micron-sized fine powder that can only be used as a processing aid. If it is a suspension copolymer, it can be used directly as a material-grade resin.

BOVC resin is a copolymer resin produced by introducing acrylate monomers into the VCM suspension polymerization process to carry out copolymerization with VC, in order to overcome the problem of poor toughness in PVC products. The modified monomers selected are primarily acrylate monomers with low glass transition temperatures; such monomers include n-butyl acrylate (BA), 2-ethylhexyl acrylate (2-EHA), ethyl acrylate (EA), etc. BOVC resin is an umbrella term for binary or ternary copolymer resins formed by the combination of vinyl chloride with these monomers. Compared to PVC homopolymer resins, copolymer resins possess a variety of excellent properties. Such as high impact resistance, excellent weather resistance, and good transparency. This copolymer resin is suitable as a resin specifically for injection molding, an impact modifier and processing additive for rigid PVC, and an internal plasticizer for soft PVC; it is a polymer material with broad application prospects.

BOVC resin is a vinyl chloride-acrylic acid copolymer resin, a chemically modified polymer material; it’s a shame to use it as an additive. Friends who are interested in discussing this further are welcome to add me on QQ: 597520190

Calling BOVC an upgraded version of ACR is not appropriate, but it can indeed be used for processing and modification. The addition of BOVC results in a decrease in the extrusion current, which is different from ACR; further research is still needed on the application of BOVC
