Lankroflex and Plas-Chek Epoxidized Oils

Lankroflex and Plas-Chek epoxidized soybean oil, Lankroflex epoxidized linseed oil and Lankroflex ED6 are secondary heat stabilizers for flexible PVC and partially replace general purpose plasticizers. The co-stabilizing effect rises with the oxirane oxygen value.

Lankroflex ED6: 4.9% oxirane oxygen
Plas-Chek 775: oxirane value 7
Plas-Chek 775: acid value 0.37 mgKOH/g

Mixed Metal Heat Stabilizers

Therm-Chek, Akcrostab, Lankromark, Lastab, Interlite and Interstab mixed metal heat stabilizers come as liquids, powders, prills and pastes for flexible PVC. Akcrostab CAZ-2020 is a liquid calcium-zinc stabilizer, and Lastab CZ 146 is a calcium/zinc stabilizer in powder form.

Liquids, powders, prills and pastes
Akcrostab CAZ-2020: liquid calcium-zinc
Lastab CZ 146: calcium/zinc powder
Phenol free grades

Tinstab Tin Stabilizers and Lankromark LE Phosphites

Tinstab and Akcrostab butyl and methyl tin stabilizers with 4–19% tin content serve rigid PVC, transparent film and sheet. Tinstab BL-277 is dibutyltin dilaurate, a liquid organotin stabilizer and catalyst. Lankromark LE liquid phosphites are 100% phenol-free.

4–19% tin content
Tinstab BL-277: dibutyltin dilaurate
Lankromark LE: 100% phenol-free
Tin catalysts for PU and silicone

Synpro Metallic Stearates and Petrac Waxes

Synpro calcium, zinc, aluminum, barium, lithium and magnesium stearates act as lubricants and acid scavengers in polymer processing. Petrac lubricants include stearic acid, paraffin, Fischer Tropsch and oxidized polyethylene waxes for rigid PVC.

Calcium Stearate 500: melting 155 °C
Calcium Stearate 500: 9.8% ash
Zinc Stearate GP: melting 120–132 °C
Petrac 215: softening 100 °C

Micro-Chek Biocides, UV-Chek and Lankrostat Additives

Micro-Chek and Intercide heavy-metal free antimicrobial agents protect PVC and PU against mildew. UV-Chek light stabilizers are AM-300 benzophenone and AM-340 hydroxybenzoate types. Lankrostat antistatic agents lower plastisol viscosity; Lubex AF 250 and AF 500 are anti-fogging agents for food film.

Micro-Chek 11: 4.0% OIT
Micro-Chek 11: soybean oil carrier
UV-Chek AM-340: hydroxybenzoate
Lubex AF 250: anti-fog for film

Fast Fusion of PVC Plastisols

Santicizer high solvating plasticizers need less energy to fuse PVC formulations: the plastisol fuses at lower oven temperatures and line speed increases.

Santicizer 160 is used as a primary plasticizer or blended with general-purpose plasticizers to offer faster fusion and lower total plasticizer loadings. Non-phthalate Platinum P-1400, P-1700 and P-1800 grades replace phthalates in plastisols, sealants, calendered and foamed products.

Santicizer 160 has a viscosity of 39 cP at 25 °C, the phosphate Santicizer 141 and 148 have 16.4 and 22.5 cP, and Platinum G-2000 has 260 cP; viscosity governs the paste behavior in spread and knife coating, dip molding and rotomolding.

Secondary Heat Stabilization of Flexible PVC

Epoxidized oils work together with a mixed metal heat stabilizer: Plas-Chek 775 provides additional acid scavenging and light stability in flexible PVC.

The co-stabilizing effect depends on the oxirane oxygen value: Lankroflex L has a high value of 8.8%, Lankroflex ED6 a lower 4.9%, but ED6 reduces plastisol viscosity and remains liquid down to -20 °C. Lankroflex L has a viscosity of 1,300 mPa·s at 20 °C; it freezes at low temperatures and melts to a clear liquid when reheated between 40 °C and 60 °C.

Tin, Waxes and Stearates for Rigid PVC

For rigid PVC the manufacturer offers Tinstab and Akcrostab butyl and methyl tin stabilizers; butyl tin grades serve pipe and weatherable applications such as window profile, siding and fencing.

External lubrication under high shear comes from Petrac 215 oxidized polyethylene wax: Mettler softening point 100 °C, acid value 16 mgKOH/g, listed in NSF/ANSI Standard 14 for plastics piping.

Synpro Calcium Stearate 500 with 9.8% ash neutralizes residual catalyst in polyolefins and reduces build up on extruder screen packs.

Esters for Cable, Low Temperature and Food Film

CEREPLAS OTM, L8TM and L810TM trimellitates have low volatility and high temperature resistance, so they are used in high-temperature PVC cable insulation, automotive interior parts and medical tubing.

DOA, DIDA and DTDA adipates bring low-temperature flexibility and low process viscosities; DOA is used in food cling wraps and DTDA in biodegradable hydraulic oils. DOS and DIDS sebacates serve underground cable sheathing in arctic environments and automotive sealants.

The phosphate Santicizer 141 and 148 are chosen where flammability and smoke limits apply.
