Description

Introduction

RotoAid is a specially modified low molecular weight polymer-based additive that works as both a nucleating agent and a lubricating agent in the rotomoulding process. Beyond reducing pinholes, RotoAid  improves polymer mixing, enhances tank surface shine and smoothness

Key Benefits

• RotoAid reduces pinholes in LLDPE tanks across all sizes and all colours, which is its headline benefit.
• It improves polymer matrix mixing, producing more consistent, defect-free material.
• It improves LLDPE granule extrusion, delivering better-quality input material.
• It improves surface shine and smoothness on both inner and outer tank layers, for a premium finish.
• It provides partial purging and extruder cleaning, keeping the machine cleaner and reducing cleaning downtime.
• It lowers the moulding temperature slightly, which saves energy and reduces polymer stress.
• It works for all colours and sizes, so one additive covers your full tank range.

Technical Features

• Chemistry: Specially modified low molecular weight polymer-based additive
• Function: Nucleating agent + lubricating agent (dual-action)
• Process: Rotomoulding (rotational moulding)
• Compatible polymer: LLDPE
• Recommended dosage: 1% of batch size (may vary with batch size, working conditions, and polymer quality)
• Addition timing: At mid-cycle of polymer matrix mixing, when the matrix becomes slightly warm
• Companion product: Used in combination with RotoChem (superfine moisture powder)
• Packaging: 25 kg bags
• Storage: Normal, dry conditions
• Quality: Manufactured under Vin Group’s ISO 9001:2015 certified system
