Why Flame Retardant PP?
Polypropylene offers relatively low density and practical processing characteristics for molded industrial components.
Standard PP may not provide the flame-retardant performance required for selected electrical, battery or industrial applications. FR PP modifies the material system to improve flame-retardant behavior while retaining useful processing characteristics.
YicaiPlas can develop formulations around application requirements, processing method, wall thickness, mechanical needs and customer validation standards.

Performance Balance
Key Performance Advantages
01
Flame Retardant Performance
Formulations can be developed for applications requiring improved flame resistance and project-specific validation.
02
Lightweight Material Platform
PP has relatively low density, supporting weight-sensitive electrical, automotive and industrial molded components.
03
Processing & Mechanical Balance
Grade direction can be optimized around injection molding, flow and required mechanical performance.
04
Application-Specific Customization
Flame-retardant level, color, flow, impact and reinforcement requirements can be evaluated for each project.
Process Evidence
Manufacturing & Quality Control
Flame retardant PP development is supported through compounding, pelletizing and performance verification workflows. Shared capability images are reused as master production assets.
02 Pelletizing
Pelletizing
Extrusion cooling and pelletizing convert compounded PP formulations into stable production pellets.
03 Performance Verification
Performance Verification
Mechanical and processing checks help verify grade consistency before customer validation.
Applications
Electrical, Automotive & Battery Applications
FR PP is considered where lightweight polypropylene processing is useful and flame-retardant performance must be reviewed against the final part design and validation requirement.
- Electrical enclosures
- Junction and control boxes
- Battery housings and protective components
- Connectors and electrical components
- Automotive electrical components
- Industrial molded housings and structural parts
Grade Direction
Available Grades
Existing FR PP grade families are organized by flame rating direction, formulation approach and target application. Final grade selection depends on application, thickness and validation.
| Grade | Flame Rating | Key Characteristic | Typical Application |
|---|---|---|---|
| YC-FR-PP-V0 | UL94 V-0 direction | Standard flame-retardant PP grade family based on existing page data. | Electrical housings, molded covers and industrial components requiring V-0 review. |
| YC-FR-PP-V0-HF | UL94 V-0 direction | Halogen-free direction for projects requesting Br/Cl-free formulation review. | Electrical, electronics and automotive components requiring halogen-free evaluation. |
| YC-FR-PP-V2 | UL94 V-2 direction | Economy flame-retardant PP direction where V-2 performance may fit the project requirement. | Cost-sensitive molded components subject to customer validation. |
| YC-FR-PP-GF20 | V-0 direction | 20% glass-fiber reinforced direction for higher stiffness requirements. | Structural molded parts where reinforcement and flame-retardant performance are both reviewed. |
Project Development
Custom Flame Retardant PP Development
YicaiPlas can review flame-retardant requirements, flow and processing adjustment, impact-performance balance, color matching, reinforcement options and application-specific formulation direction.
Final performance, certification needs and test results must be reviewed by grade, part design, wall thickness and customer validation method.
