Mineral Filled Masterbatch | Stylex International

01 Calcium Carbonate Filled

Our most widely used mineral filler — ultra-fine CaCO₃ particles uniformly dispersed in a PE or PP carrier resin. Delivers significant raw material cost savings, improved stiffness, and enhanced surface finish across films, pipes, and moulded parts.

Key Properties

Cost Reduction Improved Stiffness Better Printability Enhanced Whiteness Smoother Surface Faster Processing

Blown Films

CaCO₃ MB reduces virgin PE usage in mono and multilayer blown films, improving stiffness and opacity while maintaining excellent tear and tensile strength.

Loading: 10–30%Process: Blown FilmPolymer: LDPE / LLDPE

Carry Bags & Sacks

High-loading CaCO₃ masterbatch for shopping bags and woven sacks — significantly cutting material cost per bag without reducing structural integrity.

Loading: 20–50%Process: Blown Film / RaffiaPolymer: HDPE / PP

Injection Moulded Parts

Improves mould filling, reduces cycle time, and enhances dimensional stability in PP household goods, crates, buckets, and industrial containers.

Loading: 10–25%Process: Injection MouldingPolymer: PP / HDPE

Pipe & Conduit Extrusion

Enhances rigidity and crush resistance in HDPE corrugated pipes and conduits — allowing higher mineral loading while maintaining pressure ratings.

Loading: 15–35%Process: Pipe ExtrusionPolymer: HDPE / LDPE

02 Talc Filled

Platy talc particles provide exceptional stiffness improvement, superior heat distortion resistance, and outstanding dimensional stability — making talc-filled MB the preferred choice for automotive and technical injection moulded parts in PP.

Key Properties

High Stiffness Heat Resistance Dimensional Stability Reduced Shrinkage Improved HDT Nucleating Effect

Automotive Interior Trims

Talc-filled PP delivers the stiffness, heat resistance, and dimensional accuracy required in dashboards, door panels, and centre console parts.

Loading: 15–30%Process: Injection MouldingPolymer: PP Homopolymer

Appliance & Electronics Housings

Washing machine tubs, microwave components, and TV back panels benefit from talc's nucleating effect — enabling faster cycle times and improved surface quality.

Loading: 10–25%Process: Injection MouldingPolymer: PP Copolymer

PP Sheets & Thermoforming

Talc-loaded PP sheets for thermoformed food trays and industrial containers — providing rigidity, reduced sag during heating, and a clean white appearance.

Loading: 10–20%Process: Sheet Extrusion / ThermoformingPolymer: PP

Bumpers & Exterior Fascias

Talc-filled PP bumper systems achieve the balance of stiffness and impact resistance needed to pass automotive safety and paint adhesion standards.

Loading: 15–25%Process: Large-Part InjectionPolymer: PP + Rubber

03 Sodium Filled

Sodium sulphate and sodium bicarbonate-based masterbatches act as chemical blowing or nucleating agents in PE and PP foamed applications — enabling lightweight structures with excellent cushioning, thermal insulation, and noise damping properties.

Key Properties

Lightweight Thermal Insulation Controlled Cell Structure Weight Reduction Noise Damping Cost Saving

PE Foam Sheets & Rolls

Sodium-based MB enables a uniform, fine cell structure in extruded PE foam sheets used for protective packaging, flooring underlays, and insulation panels.

Loading: 2–8%Process: Foam ExtrusionPolymer: LDPE / LLDPE

Foamed Profiles & Planks

Lightweight PP and PE foamed profiles for door frames, decking boards, and construction trims — reducing material weight by up to 30% while maintaining structural rigidity.

Loading: 3–10%Process: Profile ExtrusionPolymer: PP / HDPE

Protective Packaging

Foamed PE sleeves, corner pads, and custom-shaped inserts for electronics, furniture, and fragile goods — cushioning impacts during transport and storage.

Loading: 2–6%Process: Foam MouldingPolymer: LDPE / PP

Automotive Foam Components

Structural foam PP parts for automotive underbody panels, boot liners, and parcel shelves — combining rigidity with weight savings critical to fuel efficiency targets.

Loading: 3–8%Process: Structural Foam MouldingPolymer: PP Copolymer

04 Barium Filled

Barium sulphate-based masterbatches offer exceptional density increase, radiation shielding, and superior chemical resistance — used in specialist applications where high specific gravity, X-ray opacity, or extreme acid resistance is a critical requirement.

Key Properties

High Density X-Ray Opacity Chemical Resistance Sound Damping Radiation Shielding Whiteness & Gloss

Medical & Radiation Shielding

Barium sulphate-filled PE films and sheets used in X-ray departments, nuclear facilities, and medical device packaging requiring opacity to radiation.

Loading: 30–70%Process: Film / Sheet ExtrusionPolymer: LDPE / PP

Automotive Sound Damping

High-density BaSO₄-loaded PP and PE sheets laminated inside car doors and floor panels to attenuate road and engine noise, replacing heavier bitumen pads.

Loading: 40–60%Process: Sheet ExtrusionPolymer: PP / LDPE

Chemical-Resistant Tanks & Liners

BaSO₄ enhances the chemical resistance of HDPE tanks and pipe linings used to store concentrated acids, alkalis, and aggressive industrial chemicals.

Loading: 20–40%Process: Blow Moulding / ExtrusionPolymer: HDPE

Premium & Luxury Packaging

Low-loading BaSO₄ MB imparts a premium weighty feel, superior gloss, and brilliant whiteness to cosmetic bottles, caps, and luxury consumer packaging.

Loading: 5–20%Process: Injection / Blow MouldingPolymer: PP / HDPE
