D1636-21 – Standard Test Method Technical Guide
The ASTM D1636-21 standard specifies the requirements for compression molding, thermosetting allyl compounds. This specification covers classification based on filler and resin composition, general requirements for uniformity, and references standard test methods for evaluation. The compounds are identified by type, class, and grade as outlined in Section 4.
📋 Classification of Allyl Molding Compounds
According to Section 4, compounds are classified into three types based on filler, with classes indicating resin composition and flame retardancy. The table below summarizes the classification.
| 🟦 Type | 📏 Class | 📐 Filler | 🎯 Resin | ⚡ Flame-Retardant | 🌟 Grades per Class |
|---|---|---|---|---|---|
| I | A | Glass | DAP | No | 4 |
| I | B | Glass | DAP | Yes | 4 |
| I | C | Glass | DMP | No | 4 |
| I | D | Glass | DMP | Yes | 4 |
| II | A | Mineral | DAP | No | 2 |
| II | B | Mineral | DAP | Yes | 2 |
| II | C | Mineral | DMP | No | 2 |
| II | D | Mineral | DMP | Yes | 2 |
| III | A | Synthetic Fiber | DAP | No | 3 |
