Dicyclopentadiene diepoxide（CAS#25053-15-0）
I. Basic Identification Information
Chemical Name: POLY(DIALLYL PHTHALATE)
CAS Number: 25053-15-0
Molecular Formula: C₁₄H₁₄O₄
Molecular Weight: 246.26
Core Properties: Solid thermoplastic polymer with unreacted allylic groups, melting point 95°C, registered on TSCA (Toxic Substances Control Act) inventory, classified as a film-forming ingredient in cosmetics
II. Clarified Safety Operation Requirements
Storage Safety: Store in a tightly sealed container, keep in a cool, dry and well-ventilated environment, avoid direct contact with high temperature and open flame
Operation Protection: Wear general chemical-resistant gloves and dust-proof masks during operation to prevent fine polymer particles from being inhaled into the respiratory tract
III. Confirmed Potential Risk Warnings
Mechanical Irritation Risk: The fine powder of this polymer may cause mild irritation to eyes and respiratory tract after direct contact or inhalation
Thermal Decomposition Risk: When heated above its decomposition temperature, it will release phthalate-related irritating fumes and carbon oxides, which may cause discomfort after inhalation
Unreacted Monomer Residue Risk: The prepolymer product may contain trace residual diallyl phthalate monomer, which has mild skin irritation and sensitization properties
IV. Supplementary Note
