Poly (butylene terephthalate) [CASRN 30965-26-5]

SECTION 2: Hazards identification

EMERGENCY OVERVIEW: • Pellets with slight or no odor. • Spilled material may create slipping hazard. • Can burn in a fire creating dense toxic smoke. • Molten plastic can cause severe thermal burns. • Fumes produced during melt processing may cause eye, skin, and respiratory tract irritation. Severe over-exposure may result in nausea, headache, chills, and fever. • Secondary operations, such as grinding, sanding, or sawing can produce dust which may present an explosion or respiratory hazard.

HMIS® ratings

Health: 0 Flammability: 1 Reactivity: 0 Skin Contact: Pellets not likely to cause skin irritation. Eye Contact: Resin particles, like other inert materials, are mechanically irritating to eyes. Inhalation: Pellet inhalation unlikely due to physical form. Processing fumes evolved at recommended processing conditions may contain trace amounts of tetrahydrofuran (typically less than 1 ppm). NTP has listed tetrahydrofuran as a carcinogen. Extreme processing conditions or temperatures may result in higher levels. See section 8 for appropriate exposure controls and personal protection. Ingestion: Pellet ingestion unlikely due to physical form. Sensitization: No information available
