Dimethylcyclosiloxane (DMC), with the chemical formula [(CH3)2SiO]x (x=3,4,5,6), is a cyclic siloxane mixture used as a key intermediate in silicone polymer production. The listing provides exact values for cyclo content (99.5% min), chroma (10 max Hazen), refractive index (1.3960 - 1.3970), and acidity (0.001% max). These are measurable technical parameters, not marketing claims.
Typical DMC grades contain a blend of D3, D4, D5, and D6 rings, with D4 being the dominant component in most industrial formulations. The low chroma and acidity indicate high purity suitable for medical-grade or high-performance silicones. The material is colorless, low-viscosity, and stable under normal storage, but must be kept away from moisture and strong acids.
DMC is primarily purchased by silicone rubber, silicone oil, and release coating manufacturers. Buyers use it as a feedstock for ring-opening polymerization. The product is packaged in 190 kg metal drums under UN1993, Class 3. Lead time and MOQ are not stated. Buyers must confirm whether the batch is intended for food-contact, medical, or industrial use, as specifications vary accordingly.

Before ordering DMC, verify the supplier provides a certificate of analysis for cyclo content, chroma, acidity, and hexamethyldisiloxane. Confirm the batch matches your intended application - medical, food-contact, or industrial - as specifications vary. Request a sample for viscosity and purity testing if your process is sensitive to impurities.
Confirm Incoterms, lead time, and packaging type directly with Hangzhou Bayee. Standard shipment is in 190 kg metal drums under UN1993, Class 3. Lead time is typically 14 - 21 days after payment. Payment terms are usually T/T or L/C. Ensure the bill of lading includes the correct hazard class and UN number.
Upon delivery, inspect drums for leaks and verify seals are intact. Test a sample for refractive index and acidity using standard ASTM methods. Retain a portion for quality control. If the product appears cloudy or has a strong odor, do not use it without retesting for degradation or contamination.
