CODE: PC/PC
Our customers have grown to expect only the highest quality products
from PMC A Division of R-SCC. This design incorporates quality with
economy. The individual conductors are insulated with extruded polyvinyl
chloride. This construction provides a product with high dielectric
strength as well as outstanding insulation resistance to ozone, acid,
alkalis, alcohol, oil, gasoline, grease, wax, moisture, and most solvents.
It is also tough and resistant to flame, abrasion, and moisture.
Polyvinyl chloride (generally referred to as PVC) compounds were commercially introduced in 1935. Three types of compounds are available; the semi rigid type, the conventional plasticized type, and the more recently developed irradiated type. Although PVC compounds can be made to provide a broad range of properties, from the standpoint of chemical, physical, and electrical characteristics, each represents a compromise. Therefore, PMC formulates its insulations to give optimum or required values to the critical properties without permitting less critical
properties to fall to unacceptable levels.
Polyvinyl chloride resin itself is non-toxic and fungus resistant but other properties of the compound may not be. It is possible with careful selection and matching of ingredients or by including special additives, to develop non-toxic and fungus resistant formulas upon request.
The thermocouple grade products are used to form temperature sensors and the extension grade products become the interconnecting link in the temperature sensing systems. We generally do not recommend PVC constructions for applications below -58°F (-50°C) because the PVC compounds stiffen as the temperature declines. Suggested operating ranges is -15°F to 221°F (-26°C to 105°C). The insulation on the individual conductors and the jacketing are both color-coded to ANSI standards for quick identification of conductors and calibration.
You will find your qualified sales and engineering staff eager to assist in selecting a design to meet the requirements of your specific application. Calibrated conductors
for high system accuracy. 221°F (105°C) PVC insulation for economy, durability and mechanical strength. 221°F (105°C) PVC jacket for economy, durability, and mechanical strength. It is also tough and resistant to flame, abrasion, and moisture.
