PVC impact modifier JC-890 Junchuang

Feature：

1.JC-890 pvc impact modifier dimethyl ester,improve melt strength,dosage is half of ACR.

2. Improve impact strength: Impact modifiers significantly improve the impact strength of PVC through mechanisms such as elastomer dispersion and core-shell structure. For example, after pre-dispersion of powdered nitrile butadiene rubber (PNBR), the impact strength can reach 52kJ/m², and after compounding CPE/ACR, it can withstand low temperature of -40℃.

3. Improve processing performance: some impact modifiers such as ACR, can enhance the stability of PVC melt flow under high shear conditions, especially for complex cross-section of the profile extrusion. ACR-modified PVC surface finish, good aging resistance, high weld corner strength.

4. Enhanced weather resistance: ACR modifier is especially suitable for outdoor use of PVC plastic products, can significantly improve its weather resistance and impact strength.

5. Reduce processing temperature: Some impact modifiers such as MBS are sensitive to processing temperature, the processing temperature needs to be controlled at 190 ℃ or less, in order to protect the integrity of its core shell and transparency.

Application:

PVC impact modifiers are widely used in many fields, mainly including the following aspects:

1. Rigid PVC products: Impact modifiers such as MBS resin can significantly improve the impact strength of PVC film, sheet, pipe, etc., while maintaining its transparency, for transparent and non-transparent products, such as food packaging film, non-outdoor pipe, etc.

2. Packaging and daily necessities: In the field of food packaging, transparent MBS resins are widely used in transparent packaging such as food containers and fresh food containers due to their high light transmittance and low haze, which are in line with FDA food contact standards. In the medium-impact type, MBS resin is used to manufacture transparent containers, light guides for lamps and lanterns, and housings for daily chemical products.

3. Electronic appliances and automobiles: MBS resin can be used to make transparent shells and precision parts for printers, refrigerators and other equipment through injection molding or blow molding. In the automotive field, high-strength MBS resins are used for automotive interior parts such as dashboard housings and exterior parts to improve impact resistance.

4. Medical and industrial: MBS resin is suitable for syringe windows, test kits and other medical supplies, and is biocompatible.
In the industrial field, chemical-resistant models of MBS resins are used for chemical pipeline linings, seals, and long-term resistance to acid, alkali and grease environments.

5. Engineering plastics modification: MBS resin is used as an impact modifier to enhance the toughness of engineering plastics such as PVC/ABS, and is suitable for the processing of plates and alloy materials. In addition, MBS resin is also used in epoxy resin adhesives to improve bonding strength and impact resistance.
