PARAFFIN WAXES

Begin with the required oil content, melting behaviour, colour and finished-product performance. The slack, semi-refined and fully refined families below offer different starting points. Share your current specification with Cerax so the proposed grade can be assessed against the intended use.

No single property describes the complete requirement. Consider the relevant oil content, hardness, processing behaviour and compatibility in the formulation. Use grade-specific technical data and consistent test methods when comparing alternatives.

Assess the candidate in your own formulation under consistent preparation and application conditions. Record the product identity, process observations and finished result. Review the outcome before increasing batch size or selecting routine supply.

Contact Cerax for current technical and safety data, product form and supply information. For application-specific requirements, discuss custom blends or review our packaging wax range.

Cerax describes slack waxes as refinery-derived materials with a range of oil contents and melting characteristics. The grade descriptions distinguish paraffinic extracts from materials with a greater microcrystalline character. This makes the exact product identity important when a buyer is comparing alternatives. A generic request for slack wax may not identify the properties needed by a coating, polish or blend.

Ask for the applicable oil-content information, temperature properties and supplied form. If flexibility or oil binding is part of the requirement, include that in the brief. Where a catalogue field is blank, request the missing value from Cerax rather than assuming it matches the adjacent grade.

The range description explains that semi-refined material is de-oiled and may be further treated to improve colour and odour. Its stated oil-content range describes a family, not a single purchase specification. Review the technical sheet for the selected product when assessing a candle, floor-polish or construction-board application.

Also check that the grade name, document and quotation refer to the same material. Descriptions such as white, translucent or industrial-use are helpful context, but they do not replace the required measurable properties. If the family heading and a grade description appear to differ, ask the technical team to clarify the classification before approving a substitute.

Cerax describes fully refined products as lower-oil materials and lists grade-specific examples for industrial and food-contact applications. Do not extend a suitability statement for one grade to the entire paraffin wax range. A request should identify the exact application and the documentation your customer or quality team requires.

For a food-contact or cosmetic enquiry, confirm the relevant requirements with Cerax before selection. The words fully refined are not, by themselves, evidence of approval for every finished product or market. Keep the confirmation for the supplied grade with your purchasing record and review it if the product identity or end use changes.

The microcrystalline description on this page emphasises flexibility, tackiness and binding properties. Those features explain why a formulator may compare a microcrystalline component with a more crystalline paraffin material. The choice still depends on the required behaviour of the complete blend, not on a general assumption that one family is better.

Describe the function you want to change and the properties that must remain acceptable. For more detail, see the dedicated microcrystalline wax range. If a combination is needed, the custom-blend enquiry can identify the target properties without prescribing a grade before evaluation.

A useful buying brief connects the grade name, agreed property limits, supplied form and applicable documents. Identify the expected order quantity and delivery requirements separately from the formulation criteria. This helps the commercial and technical discussion refer to the same product while leaving any unconfirmed details visible.

Retain the technical sheet version used for the decision, any application-specific confirmations and the trial outcome. If an alternative is proposed later, compare it with that record rather than relying only on a similar trade name or appearance. Ask Cerax to clarify any missing fields before using the catalogue as a final purchase specification.
