PVC Impact Modifiers

Product Overview

General Description

PVC impact modifiers are copolymers such as MBS (Methyl Butadiene Methacrylate), ABS (Acrylonitrile Butadiene Styrene), among others, that help rigid PVC dissipate impact energy and thus prevent fracture. PVC by itself has low impact resistance, and in applications such as water jugs or rigid profiles, these modifiers help prevent breakage and ensure product quality for the customer. Grades are available for both opaque and transparent PVC, with or without outdoor weathering properties.

Like acrylic-based processing aids, these additives increase the viscosity of the PVC melt during processing. Therefore, to prevent rapid thermal degradation, it is recommended to use one of our thermal stabilizers or lubricants.

To improve the performance of this material, reduce its dosage, and save costs, it is recommended to thoroughly review the formulation used to promote polymer melting. Certain adjustments to process conditions can also be made to achieve improvements in this area.

When manufacturing rigid PVC profiles, this additive helps prevent breakage during cutting; however, care must be taken regarding whitening that may occur during bending.

CPE-135-A

CPE-135-A is an impact modifier for rigid PVC applications. It provides good anti-caking and fast plasticizing properties, softness at low temperatures, and good mechanical properties. It is widely used in the impact modification of PVC, ACR, and MBS, as well as in magnetic materials, films, sealing strips, waterproof rolls, etc. It is also used in some rubber applications.

MB-875

MB-875 is an MBS-type impact modifier that can be used in glass applications, such as bottles and rigid film, where excellent impact resistance and chemical resistance are required.This product offers excellent resistance to oil penetration and provides very good transparency in bottles made with PVC formulations. Furthermore, its easy dispersion in these formulations ensures more consistent impact resistance and other physical properties.

LB-156

MBS LB-156 is a copolymer of methyl methacrylate, butadiene, styrene, and a quaternary functional monomer. It is characterized by its fast melting, high impact resistance, and high processing performance in PVC products.It is especially recommended for manufacturing opaque applications, such as extruded or calendered opaque films and sheets, extruded pipes and profiles for interior use, injection fittings, appliance housings, WPC, bottles, and granular PVC materials. It is not suitable for transparent applications.

LB-136

MBS LB-136 is a terpolymer of methyl methacrylate, butadiene, and styrene, primarily used in the rigid PVC process. Its main characteristics are high impact resistance, good transparency, good processability, shorter gel time, and reduced wrinkling. It can be used in opaque or transparent applications.Its rapid melting contributes to higher performance, its greater impact efficiency allows for reduced MBS dosage and cost savings in formulation, and it improves the impact properties of blow-molded PVC products, injection-molded parts, calendered laminated tubes, PVC films, laminated materials, granular materials, indoor tubes, and pipe fittings.
