Material Safety Data Sheets

This page contains all MSDS information regarding products used in our manufactured products.

up arrow


The products we produce exhibit no specific hazard due to their construction beyond the hazards associated with the components used in their manufacture.

This Material Safety Data Sheet (MSDS) is a compilation of the data contained in the individual component MSDS sheets and as such is reliant on the accuracy of those individual sheets. Under normal use there is no significant inherent hazardous exposure opportunity from the construction materials.

Fire and Explosion

Product/Compound Flash Point Extinguishing Media
Polyvinyl Chloride Compounds   Water spray, Co2 or dry chemical fire extinguisher.
Nylon 400ºC Water fog, foam, Co2 or dry chemical fire extinguisher. Fire personnel should wear turnout gear and self-contained breathing apparatus.
Cross-Link Polyethlene 650ºF Water fog, foam, Co2 or dry chemical fire extinguisher. Dense smoke emitted when burned without sufficient oxygen, possible dust explosion if fines accumulate. Fire personnel should wear standard fire fighting attire.
Aluminum 650ºF Halogen acids and sodium hydroxide in contact with aluminum may generate explosive mixtures of hydrogen. Fines will form explosive mixtures in the air and in contact with bromates, iodates or ammonium nitrate. Strong oxidizers cause violent reactions with considerable heat generation. Burning aluminum may generate carbon monoxide, carbon dioxide and ozone nitrogen oxides.

Polyvinyl Chloride Compounds

Polyvinyl Chloride Resin: 30 to 60%
Inert Fillers: 0 – 30% (CaCo3, Clay)
Heat Stabilizers: 0 – 5% (Organometallic Compounds of Lead, Calcium and/or Zinc)
Plasticizer: 20 – 40% (Phthalate esters)
Flame Retardant: 0 – 5% (Antimony Trioxide)

PVC compounds evolve Hydrogen Chloride, Carbon Monoxide and other hazardous byproducts when thermally degraded, exposure should be avoided. Exposure during handling should be controlled by wearing gloves. Washing the exposed surface can control the effects of contact with the material. Effort should be made to control nuisance dust and personal exposure to unavoidable nuisance dust limited by the use of respirators.


Routes of entry for solids and liquids include eye and skin contact, ingestion and inhalation. Routes of entry for gases include inhalation and eye contact. Skin contact may be a route of entry for liquefied gases.
Acute Overexposure Effects: Caprolactam monomer may be released during processing. Dusts generated from mechanical processing may cause irritation to the eyes, skin or respiratory tract. The OSHA TWA and the ACGIH TLV for caprolactam vapor are 5 PPM.

First Aid Procedures: Eyes: Rinse eyes with running water for 15 minutes.
Inhalation: Move to fresh air. Skin: Wash affected areas with soap and water. Remove and launder contaminated clothing before reuse. Seek medical attention if symptoms appear more than casual.


Acute Overexposure: Inhalation of fumes may cause irritation of the respiratory tract and metal fume fever with symptoms of fever, chills, nausea, chest tightness or metallic taste. Ingestion of metallic copper could be moderately irritating to the gastrointestinal tract.

Chronic Overexposure: Long term overexposure to dust or fume may cause skin irritation or discoloration of the skin and hair.

Affected Medical Conditions: Persons with Wilson’s Disease could be affected by copper exposure.

First Aid Procedures: Ingestion: Induce vomiting in a conscious individual and call a physician. Inhalation: Remove from exposure; place under the care of a physician. Skin: Flush with plenty of water. If symptoms develop, consult a physician.

Cross-Link Polyethlene Eyes: Flush for 15 minutes with water, get medical attention. Ingestion: Induce vomiting.

Eyes: Flush thoroughly with running water to remove particulate; obtain medical attention. Ingestion: If significant amounts of metal are ingested, consult physician. Inhalation: Remove to fresh air; if condition continues, consult a physician. Skin: Remove particles by washing thoroughly with soap and water. Seek medical attention if condition persists.

Reactivity Data

Polyvinyl Chloride Compounds Thermal degradation of this material produces Hydrogen Chloride, Carbon Monoxide and other common hazardous byproducts of combustion.
Nylon Incompatible with strong oxidizing agents, acids and bases. Avoid prolonged exposure to extreme heat, dust accumulation and moisture during storage. Overheating may cause decomposition and the release of Hydrogen Cyanide, Co and Ammonia.
Copper Contact with >52% hydrogen peroxide may cause a violent reaction, contact with acetylene may form unstable acetylides, copper foil burns spontaneously in gaseous chlorine and finely divided copper with finely divided halogenates may explode with heat, percussion or light friction. Hazardous oxide fumes may evolve at temperatures above the melting point.
Cross-Link Polyethlene Avoid contact with strong oxidizing agents. Decomposition generates Carbon dioxide, carbon monoxide, hydrogen bromide, methanol, oxides of antimony and trace volatile organics.
Aluminum Halogen acids and sodium hydroxide in contact with aluminum may generate explosive mixtures of hydrogen. Fines will form explosive mixtures in the air and in contact with bromates, iodates or ammonium nitrate. Strong oxidizers cause violent reactions with considerable heat generation.

Personal Protection

Polyvinyl Chloride Compounds Respiratory Protection: If dust is generated by handling. Gloves and other protective clothing: Avoid direct contact with lead stabilized compounds.
Nylon Gloves and apron to prevent contact during processing. When processing vapors are not adequately controlled, wear a NIOSH/MSHA approved organic vapor cartridge respirator. For excessive dust, wear a NIOSH/MSHA approved dust respirator. Use local exhaust to control the accumulation of dust or vapor during processing.
Copper Local exhaust ventilation is recommended for dust and/or fume generating operations. Avoid inhalation or ingestion by practicing good housekeeping and personal hygiene procedures. Where airborne exposures may exceed OSHA/ACGIH permissible air concentrations, the minimum respiratory protection recommended is a negative pressure air purifying respirator with cartridges that are NIOSH/MSHA approved against dust, fumes and mists having a TWA not less than 0.05 mg/cu.m. Protective clothing is recommended for jobs with heavy dust exposure to prevent skin irritation. Contaminated clothing should be removed before leaving the plant premises.
Cross-Link Polyethlene An approved respirator may be needed in areas with a high accumulation of fines.
Aluminum Appropriate dust/mist/fume respirator should be used to avoid excessive inhalation of particulates. Safety glasses should be worn when cutting and gloves worn when handling.

Polyvinyl Chloride Compounds Dispose of the THHN insulating material utilizing the correct procedures as required by EPA and DOT due to its Lead and Antimony Trioxide content.
Nylon This material is not regulated by RCRA or CERCLA. Incinerate or bury in a licensed facility. Do not discharge into waterways or sewer systems without proper authority.
Copper The LC50 for copper in the fathead minnow is 12 mg/L and is 3.5 mg/kg for a mouse (intraperitoneal). Acid solutions promote mobility and solubility of copper. Any method which keeps dust to a minimum is acceptable, do not use compressed air for cleaning.
Cross-Link Polyethlene Dispose of in accordance with local, state or federal regulations.
Aluminum If hazardous under 40 CFR 261, Subparts B and C, material must be treated or disposed in a facility meeting the requirements of 40 CFR 264 or 265. If non-hazardous, material should be disposed of in a facility meeting the requirements of 40 CFR 257. If discarded in an unaltered form, material should be tested to determine if it must be classified as a hazardous waste for disposal purposes.
