Acrylic Impact Modifier IM-1

Acrylic Impact Modifier IM-1 Specification

Properties
IM-1 has a special "core-shell" 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 IM-1, 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.

Physical Form
Powder

Usage
IM-1 is mainly used in rigid PVC products, especially those that need high impact resistance and good weather resistance. Examples include PVC window and door profiles, pipes. Mix IM-1 with other additives (stabilizers, lubricants, fillers, etc.) in a high-speed mixer.The mixing temperature should be reasonable to ensure even dispersion. Store the product in a cool, dry place away from moisture. After opening, keep the bag sealed and use it within one year. IM-1 has good compatibility with most additives. However, in high-filler formulas, you may increase the dosage slightly to make up for toughness loss.

Poisonous
NO

About Acrylic Impact Modifier IM-1

Acrylic Impact Modifier IM-1 is a core-shell impact modifier made for rigid PVC. Unlike ordinary impact modifiers, in the production of rigid PVC, IM-1 can greatly improve the impact toughness and low-temperature crack resistance of the final product. At the same time, it helps the material melt evenly, improves melt flow, and effectively increases surface smoothness and dimensional stability. This modifier works well with common rigid PVC additives such as stabilizers, lubricants, fillers, and pigments. It will not migrate to the surface, nor will it harm the product's original rigidity, heat resistance, or excellent weather resistance. With its reliable performance, it is especially suitable for rigid PVC products that require high impact strength, outdoor aging resistance, and processing stability, such as PVC window and door profiles, pipes, outdoor sheets, foam boards and SPC flooring.

Versatile Applications in Rigid PVC

IM-1 is tailored for rigid PVC products requiring superior impact resistance and good weather performance. Common uses include window and door profiles, and various types of pipes. Its exceptional compatibility with other additives makes it ideal for formulas where both durability and finish are crucial.

Enhance Toughness Without Sacrificing Hardness

Leveraging a unique core-shell structure, IM-1 dramatically increases impact strength while preserving the inherent hardness of PVC. This structural innovation ensures products remain sturdy, less susceptible to cracking, and resistant to brittleness, even under low temperature conditions.

User-Friendly Processing

Mixing IM-1 with other PVC additives is straightforward. A high-speed mixer and appropriate temperature ensure even dispersion. In formulations with high filler content, slightly increasing the IM-1 dosage maintains optimal toughness. Its powder form allows for easy handling and uniform integration.

FAQ's of Acrylic Impact Modifier IM-1:

Q: How should IM-1 be mixed into PVC formulations?

A: IM-1 should be combined with stabilizers, lubricants, fillers, and other additives in a high-speed mixer. It's important to control the mixing temperature for even dispersion and to achieve the best performance in the final PVC product.

Q: What benefits does using IM-1 offer to rigid PVC products?

A: IM-1 enhances impact resistance and weatherability, allowing PVC products to stay tough and resist cracking, even at low temperatures. It also contributes to a smooth manufacturing process, superior surface finish, and improved dimensional stability.

Q: When is it advisable to adjust the dosage of IM-1?

A: In PVC formulations with a high filler content, a small increase in IM-1 dosage may be necessary to compensate for any potential loss of toughness. This adjustment helps maintain the desired impact strength of the finished product.

Q: Where should I store IM-1 to ensure maximum shelf life?

A: Store IM-1 in a cool, dry place, away from moisture. After opening the packaging, reseal the bag tightly and use the product within one year to retain its full effectiveness.

Q: What is the recommended shelf life for IM-1?

A: IM-1 has a shelf life of 2 years under proper storage conditions. For the best results and safety, use the product within this period and especially within one year after opening.

Q: Does IM-1 work with most PVC additives?

A: Yes, IM-1 is highly compatible with a wide range of PVC additives. Its shell structure ensures even integration, facilitating uniform distribution throughout the PVC matrix.

Q: Is IM-1 safe to use in manufacturing?

A: IM-1 is non-toxic and safe for use in various manufacturing processes involving rigid PVC products. It does not migrate to the surface or adversely affect the final product.
