Impact-modifier solutions for tougher, more durable PVC
R&P Developments offers a wide range of PVC impact modifiers, including CPE 135A and acrylic impact modifiers for suitable PVC applications, working with established manufacturing partners to support toughness, durability and impact performance.
We help customers consider the complete formulation, manufacturing process, performance target and intended end use before exploring an appropriate impact modifier or alternative sourcing solution.
Impact-modifier selection based on the complete formulation
Impact modifiers are incorporated into suitable PVC formulations to help improve resistance to cracking or breakage when the finished product is subjected to impact. They are commonly considered where toughness, durability or performance at lower temperatures is important.
The appropriate modifier and addition level depend on more than the required impact result. PVC formulation, processing conditions, equipment, fusion behaviour, surface appearance, weathering requirements and intended end use may all influence product selection.
R&P works with customers and manufacturing partners to explore an appropriate impact modifier, possible equivalent product or alternative sourcing route based on the available technical and commercial information.
Toughness and durability
A suitable impact modifier can support improved resistance to cracking or breakage within an appropriate PVC formulation and finished application.
Processing compatibility
The modifier should be considered alongside fusion behaviour, processing temperature, equipment and the other components within the formulation.
Finished-product balance
Impact performance should be balanced with requirements such as rigidity, appearance, surface finish, dimensional stability and weathering performance.
Application requirements
Different processes and end uses require different performance characteristics. Product selection should reflect the complete application.
Solutions for different PVC performance requirements
Our impact-modifier options include CPE 135A (chlorinated polyethylene) and acrylic impact modifiers for suitable rigid PVC applications. The appropriate product and addition level depend on the formulation, processing conditions and required finished-product properties, and should be confirmed through technical review and customer trials.
General-purpose impact modification
Impact-modifier options for suitable rigid PVC formulations requiring a practical balance between processing behaviour, toughness and commercial requirements.
Enhanced impact requirements
Product options for applications requiring increased impact performance, subject to the complete formulation, processing conditions, testing requirements and intended end use.
Exterior application requirements
Impact-modifier sourcing for suitable exterior PVC applications where toughness must be considered alongside weathering performance, appearance and service conditions.
Equivalent & alternative products
Alternative-product sourcing for customers reviewing an existing impact modifier, product grade, formulation or supplier. Options are considered against technical, processing, supply and commercial requirements.
Supporting impact performance across rigid PVC applications
Impact modifiers may be used across a range of rigid PVC products. The appropriate product and formulation approach depend on the manufacturing process, equipment, required physical properties and intended end use.
Windows & profiles
Impact-modifier solutions for suitable window and profile formulations where toughness, processing behaviour, surface quality and exterior performance may need to be considered together.
Pipes & fittings
Product sourcing for suitable pipe and fitting applications where impact resistance, processing consistency and mechanical performance are important requirements.
PVC sheet & board
Impact-modifier options for suitable rigid PVC sheet and board formulations where toughness, surface appearance and finished-product performance must be balanced.
Other rigid PVC products
Product sourcing and technical discussions for other suitable rigid PVC applications, subject to formulation, processing, performance and end-use requirements.
Choosing the right impact modifier
Impact performance is influenced by the complete PVC formulation, production process and required finished-product properties. Providing relevant technical and application information helps R&P and its manufacturing partners explore an appropriate starting point.

FREQUENTLY ASKED QUESTIONS
Selection depends on the PVC formulation, manufacturing process, required impact performance, surface appearance, weathering requirements and intended application. Providing current formulation and performance information helps us explore an appropriate starting point.
An initial addition range may be available within current supplier technical information. Final addition level should be assessed through customer trials because performance depends on the complete formulation, equipment, processing conditions and required finished-product properties.
Where sufficient product, formulation and application information is available, R&P can work with manufacturing partners to explore a possible equivalent or alternative product. The customer should evaluate and validate any proposed product within their own process and finished application.
An impact modifier forms part of the complete formulation and may influence processing behaviour or finished-product characteristics. Compatibility with the formulation, equipment and required surface appearance should therefore be considered during evaluation.
Relevant technical and Safety Data Sheet information can be requested from the manufacturing partner and provided where applicable and available.
R&P does not manufacture impact modifiers in-house. We work with established manufacturing partners to source suitable products, possible equivalents and alternative supply solutions for customers.
