HotPac Moist Heat Therapy Pads

HotPac moist heat therapy pads deliver deep, penetrating warmth for pain relief, muscle relaxation, and tissue recovery in clinics, rehabilitation settings, and at home. Designed for use with a Hydrocollator heating unit, each pad is filled with a bentonite and natural hydrocolloid blend inside a durable canvas cover — the same moist-heat approach physical therapists have relied on for decades because it warms tissue more effectively than dry heat alone.

The most common question buyers ask is which size and shape fits their treatment area. This collection covers the range: the HotPac Standard Size Pad (10" x 12", 1006) handles focused areas like the lower back, shoulders, or knees, while the HotPac Oversize Pad (15" x 24", 1004) spreads heat across the full back or hip. For the neck and upper shoulders, the HotPac Contour Pad (1002) is shaped to drape and stay in place, and the HotPac 10" x 18" Heating Pad (1008) suits longer regions along the spine or legs.

All HotPac pads are reusable and rechargeable — simply return them to the Hydrocollator's hot water bath to reheat between sessions, giving facilities a durable, low-cost per-treatment solution. Wrap the heated pad in layers of terry toweling before applying to protect the skin and let the moisture pass through gradually. With proper care, a single pad withstands repeated clinical use over a long service life.
