Symptoms of severe hypocalcemia include numbness or tingling around the mouth or in the feet and hands, as well as in muscle spasms in the face, feet, and hands. Hypocalcemia can also result in depression, memory loss, or hallucinations. Severe hypocalcemia occurs when serum free calcium is under 3 mg/dL.
HeatBloc is an aluminum colored, water-based, low emissivity (low-e) coating. When applied to building materials such as plywood, OSB or plasterboard, HeatBloc lowers their surface emissivity to 0.25 or lower, thereby blocking over 75% of the radiant heat trying to enter the home. It is classified by ASTM as an Interior Radiation Control Coating (IRCC).
Heat Shrink Tubing, also called heat shrinkable tubing, is a tube that contracts when warmed. When heat is applied to the heat shrink tubing, the adhesive material inside of the tube is activated.The adhesive material then secures it to the wire or cable. The process allows the wire or cable and the heat shrink tubing to become one unified product. 2:1 - This heat shrink tubing will become half of its original size once heat is applied. 2  The original heat shrinkable tubing is twice as large as its shrunken form. 3  3:1 - This heat shrink tubing will be one third of its original size once heat is applied.
