Delamin is a strategic supplier to the Automotive Industry


Delamin is a strategic supplier satisfying the technical and logistical demands of the Automotive Industry. We supply highly consistent products within the concept of  'just-in-time', allowing customers to minimise their inventory levels. The Delamin QPQ® process (Salt Ferritic Nitrocarburizing) for metal improvement applications produces outstanding wear resistance, corrosion resistance and fatigue resistance, whilst maintaining dimensional integrity. This process is trusted in the treatment of high volume automotive components.



Acoustic Absorption Profiles

acoustic profiles aAutomotive sound proofing decreases or eliminates the effects of exterior noise, primarily engine, exhaust and tyre noise.

The introduction of lightweight inert functional fillers such as Cenospheres into bitumen profiles has enabled the development of efficient acoustic absorbing profiles. Profile thickness is reduced.

Delamin supplies Delaspheres™ (Cenospheres) for this application.

Automotive Cables

automative cablesNew levels of safety are now required for the highly regulated automotive, railway, marine and military industries.

Brominated additives have faced attention in the flame retardant cables sector. The EU has banned several types of PBDEs (polybrominated diphenyl ethers) and this substances have gradually being phased out. This change has seen the emergence of new zero halogen nitrogen flame retardants.

Delamin supplies Delflam™ for this application.

Car Body Fillers

car body fillersCar body fillers are predominantly lightweight, two-component polyester systems. Cenospheres are used in these systems as a light weight filler. Cenosphers enhance filling properties and contribute to easy sanding characteristics.

Delamin supplies Delaspheres™ (Cenospheres) for this application.

Metal Improvements

The Delamin QPQ® process together with range of Delamin Nitriding Bath products helps to achieve this. 


DEL-GEN™ PREMIUM [Nitriding Bath Regenerator Compound]

DEL-GEN™ PREMIUM is a proprietry melamine polymer used as a routine supplemental addition to an operating nitriding salt-bath to maintain the bath nitriding potential and operating efficiency. This is accomplished by the 'regenerator' reacting chemically with and converting non-desirable carbonates (sludge) formed during normal bath chemical reactions back to cyanates. 


DEL-NITE™ [Nitriding Base Salt]

DEL-NITE™ is a non-cyanide proprietary dry salt blend of alkaline and carbonate compounds formulated to meet or exceed the requirements of SAE AMS-2753C (Liquid Salt-Bath Ferritic Nitrocarburizing). It is the primary or 'base salt' for the ferritic nitrocarburizing process which is used to significantly enhance the wear resistance, corrosion resistance and fatigue properties of all ferrous materials and alloys, including cast irons and stainless steels. The process is used extensively for both automotive and appliance industry components as well as for many tooling applications in the fields of oil exploration and plastic moulding.


DEL-QUENCH™ [Oxidizing & Neutralizing Salts]

Del-Quench™ Standard is a proprietary salt consisting of alkaline nitrate and hydroxide compounds. It is used as a post-nitride 'quench bath'. This neutralises any potential cyanide compounds which may have formed as a result of nitriding bath reactions reacting with any nitriding salt residues adhering to the nitrided components or fixtures. A second and perhaps more important function from a part property and performance perspective is the formation on the part surface of a uniform Fe3O4 black oxide layer which greatly enhances the part corrosion resistance, lubricity and cosmetic appearance.

The oxidizing Quench bath is integral to the Delamin QPQ® Nitriding process.

Del-Quench™ HN [Hign Nitrate Replenishment Salt] is a higher nitrate formulation of Del-Quench™ Standard quench salt. This is used as a supplemental addition where excessive nitrate salt drag-out during normal operation tends to rapidly deplete the nitrate level below the recommended operating level of 5 % – 15 %.

Delamin® ST [Oxidizing Bath Starter Salt] is a proprietary quench salt used only when starting a new quench bath. It contains carbonate compounds in addition to alkaline nitrate and hydroxide compounds contained in the Del-Quench™ Standard composition. It is used to prevent the cosmetic problems (red surface) associated with new quench bath start-ups.



Delaspheres™(Cenospheres) are small, high strength, extremely lightweight, free flowing, non porous, hollow ceramic spheres. Cenospheres are used primarily as lightweight fillers in the oil and gas, plastics, building, refractories, automotive, aerospace and surface coating industries. Delaspheres™ are available in both grey and white to suit the intended application.


latestDelflam™ is a range of zero halogen nitrogen flame retardant synergists manufactured from melamine resulting in homologues having higher thermal stability compared to pure melamine, melamine cyanurate and melamine polyphosphate. It is non-toxic and non-corrosive.

Delflam™ is the latest development in our Nitrogen Flame Retardant programme and has now replaced the Delacal™ range. Delflam™ consists mainly of melem with a minor proportion of melam.
