Rising Star Shares Breakthrough Halogen-Free Flame Retardant Solutions for Polyolefin Materials at CHINAPLAS 2026

Advancing Halogen-Free Flame Retardant Technology for Polyolefin Applications

0
At CHINAPLAS 2026, one of the world's leading international exhibitions for the plastics and rubber industries, Mr. Liu Hui, Operations Director of Rising Star Flame Retardant Materials Co., Ltd., presented "Breakthrough Halogen-Free Flame Retardant Solution for Polyolefin Materials" during the Additives Seminar.
The seminar took place on April 23, 2026, at the National Exhibition and Convention Center (NECC), Shanghai, as part of the official Additives Seminar: Enhancing Sustainability and the Values of Plastics.
The presentation highlighted Rising Star's continued focus on developing halogen-free flame retardant technologies for polyolefin materials, supporting the plastics industry's transition toward safer, more sustainable and high-performance flame-retardant solutions.

Why Halogen-Free Flame Retardants Matter for Polyolefin Materials

Polyolefins such as polypropylene (PP) and polyethylene (PE) are widely used because of their low density, chemical resistance, processability and cost efficiency. However, achieving reliable flame-retardant performance while maintaining processing and mechanical properties remains a significant formulation challenge.
Traditional flame-retardant systems may involve halogen-containing chemistries or may require compromises in areas such as:
  • Flame-retardant efficiency
  • Mechanical properties
  • Processing performance
  • Smoke generation
  • Surface appearance
  • Material compatibility
  • Environmental and regulatory requirements
As global plastics manufacturers increasingly evaluate halogen-free solutions, the development of efficient phosphorus-nitrogen flame retardant systems for polyolefin applications has become an important area of materials innovation.

Rising Star's Approach to Halogen-Free Polyolefin Flame Retardancy

Rising Star Flame Retardant focuses on the development and manufacturing of halogen-free flame retardant additives and masterbatch solutions for plastics.
For polyolefin materials, the company's technology portfolio covers flame-retardant solutions designed for applications involving:
  • Polypropylene (PP)
  • Polyethylene (PE)
  • Polyolefin compounds
  • Flame-retardant masterbatch
  • Injection molding applications
  • Film and extrusion applications
  • Electrical and electronic components
  • Automotive and industrial plastics
  • Building and technical materials
The development strategy focuses not only on flame-retardant performance, but also on the overall balance between flame resistance, polymer compatibility, processing behavior and end-use requirements.

Phosphorus-Nitrogen Synergy for Halogen-Free Flame Retardancy

One important direction in modern halogen-free flame-retardant technology is the use of phosphorus-nitrogen synergistic systems.
Depending on the polymer system and formulation, phosphorus-based flame retardants can contribute to condensed-phase and/or gas-phase flame-retardant mechanisms, while nitrogen-containing components can provide synergistic effects.
For polyolefin compounds, the formulation challenge is particularly important because the flame retardant must work effectively within a polymer matrix while maintaining the processing characteristics required for extrusion, injection molding or other conversion processes.
Rising Star continues to develop customized flame-retardant solutions according to polymer type, processing conditions, flame-retardant target and application requirements.

Flame Retardant Solutions for PP and PE

Halogen-Free Flame Retardant for PP

Polypropylene is widely used in automotive components, electrical and electronic applications, household appliances, industrial products and other technical plastics.
Rising Star develops halogen-free flame retardant solutions for PP formulations where customers may require a combination of:
  • UL 94 flame-retardant performance
  • Halogen-free formulation
  • Processing stability
  • Mechanical-property retention
  • Low-smoke characteristics
  • Reduced dripping
  • Compatibility with reinforced PP systems
The appropriate flame-retardant system depends on the PP grade, glass-fiber content, target thickness, processing conditions and required flame-retardant rating.

Halogen-Free Flame Retardant for PE

PE presents a different formulation challenge because of its chemical structure and processing characteristics.
Rising Star is also developing halogen-free flame-retardant solutions for PE and polyolefin applications, including specialized masterbatch approaches for applications where flame retardancy must be incorporated into PE-based materials.
For film and extrusion applications, flame-retardant formulation design requires particular attention to dispersion, melt processing, film appearance, mechanical performance and the final flame-retardant requirement.

From Flame Retardant Additives to Application Solutions

Rising Star's approach is based on more than simply supplying a flame retardant powder or additive.
The company works with customers to evaluate the complete formulation system, including:
Polymer → Flame Retardant → Dosage → Processing → Flame Retardancy → Mechanical Properties → Final Application
This application-oriented approach is especially important for compounders, masterbatch manufacturers, polymer processors and plastics manufacturers developing new halogen-free materials.

Supporting the Transition Toward More Sustainable Plastics

The plastics industry is increasingly moving toward material solutions that combine performance with improved environmental and regulatory profiles.
Halogen-free flame retardant technology can support this transition by providing alternatives for applications where customers are seeking to reduce the use of halogen-containing flame-retardant systems.
At CHINAPLAS 2026, the Additives Seminar itself focused on high-value-added and sustainable additives solutions, reflecting the growing role of functional additives in improving the performance and value of plastics.
Rising Star's participation in the seminar reflects its continued commitment to developing high-performance halogen-free flame retardant solutions for modern polymer applications.

Looking Ahead

The demand for flame-retardant polyolefin materials is expected to continue expanding across areas such as:
  • Automotive plastics
  • Electrical and electronics
  • New energy applications
  • Energy storage
  • Industrial equipment
  • Wire and cable
  • Building materials
  • Technical films
  • Consumer products
As material requirements become more application-specific, flame-retardant suppliers need to provide not only products, but also formulation knowledge and technical support.
Rising Star Flame Retardant will continue to invest in halogen-free flame retardant R&D, polymer application development and customized flame-retardant solutions for PP, PE and other polymer systems.
