AXIL PLASTICS RESEARCH LABORATORIES INC.

Mold Wiz internal lubricants and processing aids are complex polymeric blends containing no wax, silicone, or metallic stearate. Nonexuding additives are mixed into thermoplastics, thermosets, and rubbers at levels of 0.1-1% by weight.

Products compounded into thermoplastic resin or dry blended by end user. Synergistic effects reduce melt temperatures and increase melt flow index for faster cycle times at lower temperatures. Improved resin flow allows easy fill of deep draw cavities, with smooth release of thin-walled parts. No warpage when releasing parts from cores or threaded molds. Better wetting of reinforcements and aided elimination of buildup, flow marks and weakness in the weld line. Molds remain clean; no solvent vapors are released. Molded parts ready for painting, bonding, printing or plating without degreasing. Many products FDA approved.

For thermosets Mold Wiz internal lubricants are mixed into gelcoat or resin and partially crosslink with resin, enhancing physical properties. Products will not diminish bond strength between laminates. Resin has better wetting properties of reinforcements and substrates, improved flow in closed molds, and easy continuous release from metal molds. While composite molds require surface treatment to seal porosity, Mold Wiz internal lubricants reportedly augment releasing properties, prolonging mold life.

WACKER SILICONES CORP.

Silicone fluids and emulsions in several viscosities recommended as internal lubricant additives for thermoplastics. Dimethylpolysiloxane fluids with viscosities of 12,500 and 30,000 cst reportedly most effective when added to most thermoplastics, including nylons and styrenics. Reported benefits include lower coefficients of friction, improved wear resistance, easier demolding, and in many cases, lower melt viscosity, which can speed injection rate and reduce cycle time.

Special functional silicone fluids and emulsions reportedly give unique lubricity and multiple release effects, or allow easier paintability. (See also Mold-Release Agents.)

WITCO CORP. ORGANOSlLICONES GROUP

(Formerly OSi Specialties) Silane coupling agents provide improved filled and reinforced polymer properties such as heat, moisture and weather resistance; improved adhesion between polymer systems and inorganic fillers and surfaces; and general durability. Silanes can also be used to convert commercial polymer matrices such as urethanes or latexes into single component moisture curable systems by means of silane crosslinking.

By adding the appropriate silane, coatings can realize improved adhesion, durability, environmental resistance, toughness and pigment dispersion. Adhesives and sealants see increased wet and dry adhesive strengths, improved hydrothermal stability and filler/pigment dispersion. In addition, sealants can benefit from improved abrasion and tear resistance, and better elongation.

Fiberglass reinforced products utilize silanes to improve impact properties, moisture resistance, wet properties and faster filler wet out. Thermoplastics reinforced with silane coupled glass or mineral exhibit superior impact, flexural and tensile strength as well as improved dimensional stability in normal, wet, detergent and excessive heat environments.

WITCO CORP. PETROLEUM SPECIALTIES GROUP

Fully refined and chemically inert USP and NF grade white mineral oils, petrolatums and microcrystalline waxes, and FDA-approved compressor lubricants reported to have excellent thermal and uv stability.

Hydrobrite Plastics Oils low-volatility white mineral oils in a wide range of viscosities and molecular weights. Products custom tailored by removing the lower boiling range molecules, thereby making them less volatile. Lower volatility offers such benefits as reduced die sweat, reduced overhead loss/emissions, reduced fogging and reduced oil loss.
