Plastics & Polymers

Bulk handling for plastic pellets,
powder, and masterbatch systems.

Plastic resins, pellets, and compound powders have specific flow characteristics that demand careful system design. Electrostatic build-up, angel hair generation, and streamers in pneumatic systems are common failures when equipment is poorly selected.

Industry Challenges

The problems that need engineering — not workarounds.

⚡
Electrostatic Build-Up
Plastic pellets and powders generate significant static charge during pneumatic conveying. Without proper earthing, anti-static pipe, and grounding straps, electrostatic discharge can cause fires or shocks.
🪄
Angel Hair & Streamers
High-velocity conveying causes pellet friction against pipe walls, generating 'angel hair' streamers that contaminate the product. Correct velocity selection — typically dense phase for pellets — eliminates this.
🔄
Colour and Grade Changeover
Masterbatch and compound plastic producers change colours and grades frequently. System design must minimise changeover time and prevent cross-contamination through efficient purging sequences.
ENZAC Solutions

How we solve them.

01
Dense Phase Pellet Conveying
Low-velocity dense phase for plastic pellets eliminates angel hair generation and pellet attrition. Ceramic-lined bends at every direction change. Air-to-material ratio engineered for your specific pellet density.
02
Anti-Static System Design
Earthed stainless or conductive HDPE conveying pipe with grounding continuity testing. Anti-static flexible hose connections. ESD-protected filter units. Static dissipative boot seals on all connections.
03
Colour Changeover — Rapid Purge Design
Straight-through valve configurations and purge air injection points minimise colour contamination during product changes. Documented purge sequence for each grade combination.
04
Big Bag Discharge for Masterbatch
Controlled FIBC discharge with bag massage, load cell weighing, and colour-coded connection systems. Dust-tight to prevent cross-colour contamination in masterbatch operations.
Capability Focus · Plastics & Polymers
Plastics handling — engineering out angel hair and static from day one
Angel hair and electrostatic discharge are not operational problems — they are design problems. ENZAC designs plastic handling systems with correct velocity selection, anti-static specification, and purge systems from the engineering phase, not as afterthoughts added after commissioning failures.
  • Dense phase design for pellet conveying
  • Anti-static specification throughout
  • Rapid colour changeover purge systems
  • ESD grounding verification testing
