Abordagem de solução
RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.
Typical Selection Workflow
1
Process & Requirement Definition
Map the unit operation and define the functional, purity, and regulatory requirements the chemical input must meet.
2
Chemistry & Grade Selection
Match the solvent, intermediate, acid or base, catalyst, or specialty additive to the process and downstream compatibility.
3
Trial & Specification
Validate performance at bench or pilot scale, and set the grade, treat rate, and packaging to match throughput and handling.
4
Quality & Supply Assurance
Lock the spec with a CoA and secure multi-origin sourcing for supply resilience and consistent lot quality.

Polypropylene Glycol (PPG-26) Flotation Frother
CAS 25322-69-4
Glicóis e Polióis
Non-silicone defoamer and process aid
PPG-26 is polypropylene glycol, a propylene-oxide homopolymer (it contains no ethylene oxide). Its inverse-solubility cloud-point behavior lets it enter and destabilize foam lamellae as a silicone-free defoamer base, used where silicone carryover onto plating/paint-sensitive parts must be avoided
