PRODUCT DESCRIPTION

SN-350 is a fine, non-dusting white powder, which acts as an efficient high-temperature lubricant and a high-performance stabilizer for PVC processing. It is invariably used in combination with primary lead stabilizers like TBLS (SN-310/311), DBLF (SN-320), and DBLP (SN-330) to complement for their non-lubricity.

FUNCTIONAL BEHAVIOR AND SALIENT FEATURES

• SN-350 is normally used in combination with primary lead stabilizers.
• SN-350 provides very good long-term heat stability in colored flexible PVC products and an excellent inner surface finish in extruded rigid PVC products.
• It has excellent synergism with other metallic stearates and is therefore recommended for long-term heat stability in colored PVC cable coverings.
• SN-350 forms an ideal combination with SN-310 and SN-320 for the production of rigid and semi-rigid PVC products for indoor and outdoor applications.
• SN-350 alone is recommended in some transparent flexible products.

RECOMMENDED DOSAGE

1-3 phr

PACKING

25 KG in laminated HDPE bags

HANDLING & STORAGE

• Use hand gloves and dust masks while handling SN-350.
• In case of fire, use sand and inorganic chemical-based fire extinguishers.
• SN-350 must be stored in dry, well-ventilated, cool places away from hot surfaces and direct sunlight.
• Partially used bags must be closed properly after use.
