Type HP meets IEEE 1493 performance criteria. 1 It effectively cleans semi-conducting cable shield. A towel saturated with cleaner quickly removes the compound and becomes visibly black.
PROPERTY RESULT Cleaning effectiveness Excellent Dielectric strength 100-mil gap (ASTM D877) >40kV Evaporation rate Medium Residue (ASTM D2369) <100 ppm Physical compatibility (XLPE, EPDM, silicone rubber) Pass Volume resistivity Pass
Tested using methods from IEEE 1493, “Guide for the Evaluation of Solvents Used for Cleaning Electrical Cables and Accessories.- End Use
- Transformers, switchgear
- Motor control devices
- Fusible disconnecting devices
- Wind turbine nacelles
- Motors, generators, and rheostats
- Direction For Use
- Type HP is suitable for many types of cleaning and degreasing. It is effective at room temperature and does not freeze; it can be used in cold weather applications.
- Cleaning time and effectiveness will vary based on the contaminant and cleaning method. Wiping or agitation cleans faster than just soaking. Experiment with your particular contaminant and conditions.
- Type HP leaves no residue. For precision cleaning, a final rinse of fresh cleaner should be used. Finish with a fresh wipe, spray until the solvent runs clear, or rinse in a fresh bath of Type HP cleaner.
- For faster drying, air or centrifugal dryers can be used to accelerate evaporation. Wiping the part with an absorbent, lint-free towel will reduce drying time considerably.

Technical Details & Test Data
- Cleaning Properties
Type HP dissolves a broad range of contaminants. A contaminant is added to 20 grams of cleaner at ambient temperature. The quantity dissolved is recorded.
CONTAMINANT AMOUNT DISSOLVED PCB (Aroclor 1260) 10 grams Cutting oil (Rigid Nu-Clear, sulphurized oil) 10 grams Silicone grease (Dow Corning 4 Compound) 2 grams Animal oil (Lanolin-Tech Grade) 2 grams - Compatibility
Type HP is compatible with most common plastics and rubbers. It meets standard electrical utility test requirements based on IEEE 1493.
- Plastic Materials - XLPE XLPE jacket material immersed in Type HP retains tensile and elongation characteristics and shows minimal weight change.1
- Plastic Materials - Polycarbonate Does not stress-crack polycarbonate plastic. After a 15-minute soak in Type HP, polycarbonate withstands >0.9% strain without cracking.2
- Rubber Materials - EPDM and Silicone Rubber Platen samples of EPDM and silicone rubber immersed in Type HP retain tensile and elongation characteristics and show minimal weight change.1
- Volume Resistivity of Cable Insulation Shield Type 0691 XLPE immersed in Type HP shows acceptable volume resistivity values.1 After exposure to the cleaner, volume resistivity measurements return to control levels.
- Corrosivity Type HP will not corrode or stain metal parts. It does not tarnish or corrode copper.3

- 3Testing based on ASTM D130, “Standard Test Method for Detection of Copper Corrosion from Petroleum Products by the Copper Strip Tarnish Test.”
- Soak Testing
Materials are immersed in Type HP for 72 hours at 50°C (122°F). Some rubbers will swell but should return to their original state once the cleaner evaporates. Wipe cleaning minimizes solvent exposure.

- Model Specification
- The cleaning solvent shall be Polywater Type HP Cleaner. Cleaner shall contain at least 80% highpurity, dearomatized, aliphatic hydrocarbon enhanced with a cyclic terpene. Aromatic content shall be less than 1%. Water content shall be less than 50 ppm.
- The cleaner shall not leave a residue. The cleaner shall not significantly affect the volume resistivity of Union Carbide 0691 XLPE cable insulation shield. The cleaner shall have a good dielectric strength, at least 40 kV when tested by ASTM D877 with a 100-mil (2.5 mm) gap.
- The cleaner shall not significantly affect the tensile and elongation properties of XLPE, silicone rubber, and EPDM rubber when tested to guidelines proposed in IEEE P1493. When wiped over an XLPE (Union Carbide Type 0691) insulation shield, a clean towel wetted with the cleaner shall become visibly “black” with two wipes over 2 inches (50 mm) of cable length with light hand pressure.
- The cleaner shall not be a carcinogen or listed by CERCLA as a hazardous waste. It shall not be on the EPA Phase I or Phase II list of banned or phased-out chlorofluorocarbons.
Safety & Health
- Safety
Type HP has a low level of toxicity and contains no listed carcinogens. It is combustible and should not be exposed to fire or flame. Good industrial hygiene practice and appropriate precautions should be employed during use. Type HP is a safer alternative to chlorinated solvents.
PROPERTY RESULT VOC content 790 grams/liter Persistence Biodegradable Global warming potential Does not contain global
warming compounds.Ozone depletion potential None RCRA Not regulated as
hazardous waste.CERCLA/SARA status Not regulated as a
hazardous substance.The Type HP presaturated towelette is a convenient package with multiple safety benefits.
Control
Presaturated wipes minimize solvent exposure on sensitive electrical parts. Directly spraying or immersing the part allows the solvent to seep into small openings. Wipe cleaning also ensures faster solvent evaporation.
Safety
The presaturated towelette package eliminates spill hazard and limits solvent vapor exposure. Wipes contain a carefully measured quantity of solvent and are an excellent way to control vapor. Type HP presaturated towelettes are a great choice for underground or confined space applications.
Convenience
Each package utilizes non-linting, nontearing towels. Clean wipes are always available, eliminating recontamination of parts with dirty rags. Custom kits may include extra dry towels or abrasive cloth as needed.
