Atactic Polypropylene (APP) APP-130

Model: APP-130

CAS No.: 9003-07-0

1. Product Description

Atactic Polypropylene (APP) is a unique amorphous synthetic material. It is used as a modifier for bitumen waterproof membranes; as powder coating carrier and dispersing additive for filler masterbatch and color masterbatch; as plasticizing aid modifier for PVC footwear compounds. It is also applicable to hot melt adhesives, sealants, anticorrosive coatings and rubber-plastic blend modification systems.

2. Typical Specifications

Note: The above are typical reference values only, not guaranteed specifications. Reasonable batch-to-batch variations are acceptable.

3. Recommended Dosage & Applications

• PVC footwear compound: 2~6 phr. Improves filler dispersion and toughness, delivers smooth surface and reduces blooming.
• Filler / color masterbatch carrier: 10~25% of total masterbatch weight, high-filling coating carrier.
• Bitumen waterproof membrane: 5~12%, improves high-temperature anti-flow resistance and low-temperature crack resistance.
• Hot melt adhesive base material: Formulate as required to enhance cohesion and adhesion.

4. Processing Guide

• Processing temperature range: 140~180℃
• Recommended mixing/extrusion temperature: 150~170℃. Melt APP first to wet fillers before blending with other components.

Features: Lubrication & dispersion, plasticization assistance, toughening, higher filler loading capacity. Do not hold temperature above 200℃ for prolonged time to avoid thermal degradation and yellowing.

⚠️ Caution: Long-term exposure above 200℃ will cause APP thermal degradation, yellowing and emission of low-molecular volatile fumes.

5. Packaging, Storage & Shelf Life

• Packing: 25 kg / bag, PP woven bag with PE inner liner.
• Storage: Store in cool, dry and ventilated warehouse, away from open flame and strong oxidants. It tends to soften and stick together under high temperature. Seal tightly after opening.
• Shelf life: 12 months in unopened original package under recommended storage conditions.
