HYDLAR possesses a combination of physical properties that cannot be found in any other commercially available engineered plastic. Ensinger engineers have created a family of superior wear and abrasion resistant thermoplastics using aramid fiber reinforced polymer. This technology makes possible for aramid fiber reinforced plastic to be used in combination with a nylon base resin.

Safety
Hazards Identification
EMERGENCY OVERVIEW: Mechanical injury only.
ROUTES OF ENTRY: Eyes
POTENTIAL HEALTH EFFECTS
EYES: Solid or dust causes irritation or corneal injury due to mechanical action.
SKIN: Essentially nonirritating to skin. Mechanical injury only. Molten material may burn skin.
INGESTION: Single dose oral LD50 has not been determined. Single dose oral toxicity is believed to
be very low. Now hazards anticipated from ingestion incidental to industrial exposure.
INHALATION: Dust may cause irritation to upper respiratory tract. At room temperature, exposure to
vapors are unlikely due to physical properties, normal processing temperatures may
generate vapors, which may cause irritation if ventilation is inadequate.
ACUTE HEALTH HAZARDS: None Known
CHRONIC HEALTH HAZARDS: None Known
Particulates
OSHA: Particulates not otherwise regulated/OSHA (PEL) 15 mg/m3
(TWA, Total Dust)
Particulates not otherwise regulated/OSHA (PEL) 5 mg/m3
(TWA, Respirable Dust)
ACGIH: Particulates not otherwise regulated/ACGHI (TLV) 10 mg/m3
