Superior Impact Enhancement for Rigid PVC

PVC Impact Modifier is formulated to dramatically increase the impact strength and toughness of rigid PVC goods. Its advanced composition, including acrylics, CPE, or ABS, makes it an essential additive for demanding applications like pipes, profiles, and window frames. Its excellent compatibility ensures smooth blending during production, resulting in durable, crack-resistant finished products.

Excellent Heat and Weather Resistance

Thanks to its outstanding thermal and weather-resistant properties, this impact modifier performs reliably even under harsh environmental conditions. It remains stable at temperatures above 200C and helps finished PVC goods maintain integrity and color despite prolonged outdoor exposure. This ensures long-lasting results and minimizes product failures.

Safe, Versatile, and Easy to Use

Non-toxic and compliant with strict safety standards, PVC Impact Modifier is safe for use in diverse environments. It is easy to handle in its powdered form, mixing smoothly with PVC resin at a recommended dosage of 5-10 phr before extrusion or molding. Store in a cool, dry space to preserve maximum effectiveness over its two-year shelf life.

FAQ's of PVC IMPACT MODIFIER:

Q: How should PVC Impact Modifier be used in PVC processing?

A: PVC Impact Modifier should be thoroughly mixed with PVC resin at a dosage of 5-10 parts per hundred resin (phr) before extrusion or injection molding. This ensures uniform dispersion and optimal enhancement of impact strength.

Q: What benefits does the impact modifier provide in rigid PVC products?

A: It substantially improves impact strength and toughness, boosts weatherability, and enhances the processability of PVC. This leads to longer-lasting, crack-resistant products such as pipes, window frames, and profiles.

Q: When is the ideal time to add the impact modifier during the production process?

A: The impact modifier should be added and blended into the PVC resin prior to extrusion or molding to ensure homogenous integration and maximize performance advantages in the final product.

Q: Where can the PVC Impact Modifier be applied most effectively?

A: It is best suited for rigid PVC items requiring high impact resistance, like pipes, fittings, sheets, profiles, and window frames, especially in applications demanding durability and toughness.

Q: What makes this impact modifier compatible with PVC and various additives?

A: Its specialized formulation with acrylics, CPE, or ABS ensures high compatibility with PVC resin and most plasticizers, allowing easy blending without affecting the clarity or properties of the base material.

Q: How should the PVC Impact Modifier be stored for optimal shelf life?

A: Store the powder in a tightly sealed container in a cool, dry environment to maintain its effectiveness and stability for up to two years from the date of manufacture.

Q: Is the PVC Impact Modifier safe and environmentally compliant?

A: Yes, it is non-toxic, odorless, RoHS compliant, and free from hazardous substances, ensuring safe processing and end use in various industrial applications.

Acrylic Impact Modifier IM-60

Price 1850.0 USD ($) / Ton

Minimum Order Quantity : 1 Ton

Physical Form : Powder

Shelf Life : 2 Years

Product Type : Acrylic Impact Modifier

Properties : Acrylic Impact Modifier IM60 is a white coreshell copolymer powder tailored for rigid PVC modification. Its special layered structure enables highefficiency impact reinforcement both at ambient temperature and low temperature, requiring only small addition amounts to upgrade PVC toughness significantly. Thanks to its allacrylic saturated structure, it outperforms CPE and MBS in weather and UV resistance, resisting yellowing and cracking under prolonged outdoor sunlight and humid heat. This modifier shows great compatibility with all mainstream PVC stabilizers including calciumzinc and lead salts. It facilitates smooth plasticization during processing, expands the allowable processing temperature range, and supports highspeed extrusion. End products added with IM60 gain glossy, flawless surfaces with few fisheyes, so the product is widely adopted for outdoor plastic steel profiles, pvc pipes, profile PVC products fitting and SPC flooring.

Acrylic Impact Modifier IM-1

Price 1849.0 USD ($) / Ton

Minimum Order Quantity : 1 Ton

Physical Form : Powder

Shelf Life : 2 Years

Product Type : Acrylic Impact Modifier IM1

Properties : IM1 has a special "coreshell" structure. The core is a very soft rubber that can absorb and spread out impact force. The shell has good compatibility with PVC and can spread evenly in the PVC. This structure helps improve toughness without damaging the original hardness of PVC. After using IM1, the impact resistance of PVC products is clearly improved. Even in low temperatures, the products are less likely to become brittle or crack. At the same time, it makes processing smoother, gives products a better surface finish, and improves dimensional stability. Also, it will not migrate to the surface, and it will not affect the product's heat resistance or sunlight resistance.
