Micro-foaming agent · foaming agentNitrogen foaming system · micro-cells invisible to the eye · can make foaming colour masterbatch
A high-efficiency micro-foaming agent developed specifically to change plastic weight and reduce part density. Adding ACM750 to a conventional filler masterbatch produces a micro-foaming filler masterbatch that largely removes the density (specific gravity) penalty of conventional filler masterbatch, cutting production cost more effectively.

Four advantages over conventional filler masterbatch
The bars are measured comparison values from the source file; they expand automatically when scrolled into view.
Excellent thermal insulation
In agricultural film, the thermal insulation of the micro-foaming filler masterbatch is more than 50% better than a conventional filler masterbatch.
Reduced thermal deformation
In profiles, thermal deformation resistance is 60% better than a conventional filler masterbatch.
Adjustable density · down to −15%
Depending on the required specific gravity, density can be matched to the plastic or even brought 15% below the original plastic.
Reinforcement and better handfeel
Too much conventional calcium carbonate filler leads to a poor handfeel and lack of rigidity; too much talc damages heat-seal performance. The ACM750 micro-foaming filler masterbatch largely eliminates this whole set of defects.
Multi-function extension:It can be made directly into a foaming colour masterbatch, widely used for foaming and modification of all kinds of plastic products.
Micro-cells invisible to the eye · only visible under a magnifier
Mainly used for microcellular foaming invisible to the eye in plastics — to make microcellular filled masterbatch, foaming masterbatch and the like: the surface stays smooth while the density quietly drops.

01Product positioning
Name and positioning. The data page is titled 'Foaming agent ACM750'; the main use is recorded as 'mainly used for microcellular foaming of plastics invisible to the naked eye, microfoaming filled masterbatch is foaming masterbatch, etc.'; application field 'Plastic microfoaming'. (Data source: product handbook)
Overview (quoted verbatim): 'Microfoaming agent ACM750 is a microfoaming agent developed by our company in response to market demand to change the weight of plastics. For example, the microfoaming filled masterbatch produced by adding the microfoaming agent on the basis of producing ordinary filled masterbatch compensates for the effect of filled masterbatch on plastic density (specific gravity), and more effectively reduces production costs. Compared with ordinary filled masterbatch, the thermal insulation performance of microfoaming filled masterbatch used in agricultural film is 50% better. Another example is for packaging films: if too much ordinary calcium carbonate filled masterbatch is added, it affects the hand feel and makes it lose rigidity; if too much talc filled masterbatch is added, it affects heat-sealing performance. Microfoaming filled masterbatch almost compensates for this series of defect issues. The thermal deformation rate for profiles is 60% better than that of ordinary filled masterbatch. According to product specific gravity requirements, it can be adjusted to the same specific gravity as the plastic or even a specific gravity 15% lower than that of the original plastic. It can also be made into foaming color masterbatch for direct use in various plastics.' (Data source: product handbook)

02Formulation system & mechanism of action
Gas-generation pathway. The data records that this product releases nitrogen at a decomposition temperature of 160℃, with a gas yield of 75-96 ml·g⁻¹ — the gas forms microvoids invisible to the naked eye within the plastic matrix. (Data source: product handbook)
Composite system. As a microfoaming agent, it is used to prepare 'microfoaming filled masterbatch' on the basis of ordinary filled masterbatch, changing the density (specific gravity) and cost structure of products through the microvoid structure; the data records that 'according to product specific gravity requirements, it can be adjusted to the same specific gravity as the plastic or even a specific gravity 15% lower than that of the original plastic'. (Data source: product handbook)
Form and processability. The appearance is a flowable yellow viscous liquid with an ether odor (molecular weight 6500-7300), suitable for filled masterbatch and foaming color masterbatch processes; it can also be made into foaming color masterbatch for direct use in various plastics. (Data source: product handbook)
- Mixing in — microfoaming filled masterbatch systemAdd the microfoaming agent on the basis of ordinary filled masterbatch to prepare microfoaming filled masterbatch (or foaming color masterbatch).
- Gas generation — nitrogen microvoid formationAfter the processing temperature reaches the decomposition temperature of 160℃, nitrogen is released, forming microvoids invisible to the naked eye.
- Specific gravity setting — balancing cost reduction and performanceAdjust the proportion of microvoids according to specific gravity requirements; the data records improvements in agricultural film thermal insulation, profile thermal deformation rate, hand feel, heat-sealing performance, etc.

04Recommended dosage window
The source gives one range for the addition of this product:
| Scenario | Dosage | Conditions & notes |
|---|---|---|
| Dosage | 0.5%-10% | Source text: "[Dosage] 0.5%-10%"; the denominator is not specified (reproduced as-is, not inferred) |
The source provides only one range and does not specify the denominator; it is presented as-is and the denominator is not inferred. The range is relatively wide (0.5%–10%); the value depends on the masterbatch formulation, target specific gravity, and processing technology, and should be determined by small-scale trials.
This is the only dosage record for this grade in the source; there is no second line and no scenario-specific tiers; this page does not infer the denominator and does not convert across grades. (Data source: product handbook)

06How it differs from related grades
ACM750 and F818 both belong to the microcellular foaming direction and are commonly used as a pair; the two grades differ in released gas and technical specifications, so select according to the target. Comparison as follows:
| Grade | Documentation positioning (key points) | Key technical specifications | Dosage (as recorded in documentation) |
|---|---|---|---|
| ACM750 | Microcellular foaming agent that changes plastic weight; 'for profiles, the heat deformation rate should be better than that of ordinary filled masterbatch by 60%'; specific gravity can be adjusted to 15% lower than the original plastic | Appearance: yellow viscous flowable liquid with an ether odor; Gas evolution: 75-96 ml·g⁻¹; Decomposition temperature: 160℃; Released gas: nitrogen; Molecular weight: 6500-7300 | 0.5%-10% |
| F818 | Microcellular foaming agent developed to change the direction of conventional plastic ordinary filled masterbatch; 'specific gravity 10% lower than the original plastic'; used for film and bag applications | Appearance: white viscous flowable liquid with an ether odor; Gas evolution: 45-48 ml·g⁻¹; Decomposition temperature: 160℃; Released gas: carbon dioxide | 0.5%-1.5% |
Reading note: both grades are in the microcellular foaming direction, but the released gas (nitrogen / carbon dioxide), gas evolution, and dosage ranges differ; values must not be applied interchangeably. (Data source: product handbook)
