EXOLIT OP 1230

Product Details

Exolit OP 1230 is a white, fine-grained powder based on an organic phosphinate. The product is non-hygroscopic and it is insoluble in water and organic solvents. Clariant’s Exolit OP flame retardants for polyamides are all based on aluminium diethyl-phosphinate (= DEPAL). The pure substance DEPAL is sold as Exolit OP 1230 and in combination with synergists as Exolit OP 13xx types. Exolit OP 1230 is the first non-halogenated flame retardant which can withstand the demanding requirements of this high end segment of engineering plastics.

Benefits

• Non-hygroscopic, insoluble in water and organic solvents
• Good hydrolysis resistance
• Suited as flame retardant for thermoplastics and thermosets
• High efficiency due to its high phosphorus content
• UL 94 V-0 rating down to 0.4 mm thickness
• Suited for processing temperatures up to ~ 330 °C
• Suitable for both glass fiber reinforced and unreinforced grades
• The flame retardant polyamide compounds exhibit very good physical and excellent electrical properties
• Suitable for lead free soldering
• Good colorability
• Non-halogenated flame retardant with favorable environmental and health profile

Typical Applications

Exolit OP 1230 is suited as flame retardant for thermoplastics and thermosets. Due to its high phosphorus content the product is distinguished by a high efficiency. 

Exolit OP 1230 can even be applied in high temperature polyamides because of its high temperature stability. It is suitable for both glass fibre reinforced and unreinforced grades. The flame retardant polyamide compounds exhibit very good physical and electrical properties. 

In high temperature polyamides of PA 6T/66 type, a dosage of approx. 15 % (by wt.) Exolit OP 1230 is usually sufficient to obtain the UL 94 V-0 classification for electrical compounds (at 1.6 as well as 0.8 mm thicknesses). Subject to the polymer grade, processing conditions and glass fibre reinforcement the dosage of the flame retardant may vary.
