Controlled foaming solutions for PVC processing
R&P Developments supplies specialist blowing-agent packs for PVC applications, working with established manufacturing partners to support controlled density reduction, consistent cellular structure and reliable processing.
We help customers consider the formulation, process, performance target and end-use requirements before exploring a suitable product or tailored sourcing solution.
Blowing-agent selection based on the complete application
Blowing agents are used to create a cellular structure within a polymer during processing. In suitable PVC applications, this can support controlled density reduction while influencing cell formation, surface quality and final-product performance.
The appropriate solution depends on more than the blowing agent alone. Polymer formulation, processing temperature, equipment, melt behaviour, target density and end-use requirements can all influence product selection and performance.
R&P works with customers and manufacturing partners to explore an appropriate blowing-agent pack, equivalent product or tailored sourcing route based on the available application information.
Controlled density reduction
Blowing-agent systems can support reductions in product density where foaming is technically appropriate for the formulation, process and intended application.
Cellular consistency
The choice of blowing-agent system and processing conditions can influence cell size, distribution and consistency within the finished product.
Processing behaviour
Dispersion, activation profile, melt strength and flow behaviour should be considered together when evaluating a blowing-agent solution.
Application-specific support
Every formulation and production line is different. R&P helps customers review relevant technical and commercial factors before exploring a suitable option.
Blowing-agent packs for different PVC requirements
The RPCELL range includes blowing-agent packs developed for different processing, density and application requirements.
The descriptions below provide a general introduction. Final suitability, addition level and processing conditions should be confirmed using current technical information and customer trials.
RPCELL 001
A standard blowing-agent pack developed for suitable PVC profile-extrusion applications.
Product suitability and addition level depend on the formulation, process and physical properties required.
RPCELL 002
An enhanced option within the RPCELL range for applications seeking a lower-density target than the standard RPcell 001 approach.
Final selection and addition level should be evaluated against the customer’s formulation and processing conditions.
RPCELL 005
A composite blowing-agent pack incorporating supporting additives alongside the blowing-agent system.
Developed for applications where melt behaviour, die flow and processing consistency are important considerations.
RPCELL 006
A microgranular blowing-agent option developed for foam-core pipe applications.
The product form is intended to support clean handling and consistent addition within an appropriate PVC formulation.
RPCELL 012
A specialist blowing-agent pack incorporating a balanced combination of blowing-agent and process-support components.
Designed to support powder flow, controlled cell development and consistent processing.
Supporting cellular PVC production requirements
Blowing-agent systems may be used across a range of cellular PVC applications. The correct product and processing approach depend on the formulation, equipment, target properties and intended end use.
PVC SHEET & BOARD
Blowing-agent solutions for suitable cellular PVC sheet and board formulations where controlled density reduction, consistent cell development and surface quality are important considerations.
FOAM-CORE PIPES
Blowing-agent solutions for suitable foam-core pipe formulations where controlled cellular development and processing consistency are required.
PVC PROFILES
Blowing-agent packs for suitable profile-extrusion applications where density, cell structure and surface quality must be considered together.
Choosing the right blowing-agent solution
Blowing-agent performance is influenced by the complete formulation, production process and required finished-product properties.

FREQUENTLY ASKED QUESTIONS
Selection depends on the PVC formulation, process, activation requirements, target density, cellular structure and finished-product properties. Providing process and application information helps us explore an appropriate starting point.
Indicative information may be available from current technical documentation, but the appropriate addition level must be evaluated within the customer’s formulation, equipment and processing conditions.
Yes. Where sufficient product, formulation and process information is available, we can explore equivalent or alternative products through our manufacturing and supply partners.
Relevant Technical Data Sheets and Safety Data Sheets can be provided where applicable and available. Contact us with the product name and destination market so that we can identify the appropriate documentation.
R&P Developments is a specialist supplier and technical partner. Products are sourced or manufactured through third-party manufacturing partners rather than produced at an R&P manufacturing facility.
