● Remarks
1. GSM1A-1 is treated without silicone or treated with pretty light silicon oil.
2. GSM1A-1 is mainly used in air heating with wattage loading less than 9W/cm2.
3. Electrical grade MgO powder is non-toxic, but with some dust. It is recommended to wear anti-dust respirators and gloves during operation.
4. The elements can stand 1050℃ annealing for 15-30 minutes and requires immediate sealing.
5. Electrical grade MgO powder should be stored in dry places, and best used within 6 months after delivery.
