TRUNNANO Powder Foaming Agent Announced: Overcoming Technical & Transportation Challenges

TRUNNANO powder foaming agent: stable foam, minimal strength loss, non-flammable, dust-free. Ideal for foamed concrete, aerated blocks, mortars.

LUOYANG, CHINA, September 3, 2026 /EINPresswire.com/ — TRUNNANO (Luoyang Tongrun Info Technology Co., Ltd), a national high-tech enterprise specializing in concrete admixtures, has introduced a new solid powder foaming agent designed for lightweight concrete production. The product is now available for applications including foamed concrete, aerated blocks, lightweight panels, and specialty mortars.

Background and Product Positioning

The construction materials industry has seen sustained demand for lightweight and energy-efficient building solutions. Foaming agents are a key component in producing foamed concrete, aerated blocks, and lightweight panels, contributing to reduced structural dead load, thermal insulation, and sound absorption. The global foamed concrete market has experienced steady growth in recent years, driven by regulatory emphasis on building energy conservation and the adoption of green construction practices across major economies. Industry analysts project continued expansion as urbanization accelerates in developing regions and retrofit projects increase in mature markets.

However, conventional liquid foaming agents present logistical challenges, including high transportation costs, limited shelf life, and on-site handling requirements. Existing powder alternatives have also faced issues related to dust generation and mixing uniformity.

According to industry data, transportation costs for liquid foaming agents can account for 30–50% of total procurement costs for projects located more than 500 kilometers from manufacturing facilities. In tropical climates, liquid agents may experience up to 40% reduction in foaming capacity after six months of storage. These constraints have historically limited the feasibility of lightweight concrete applications in remote or cross-border infrastructure projects.

Technical Approach

TRUNNANO’s newly released powder foaming agent utilizes a composite surfactant system combined with carrier loading technology. The active ingredients are loaded onto solid carriers through spray granulation, then dried, crushed, and sieved. This process produces a free-flowing, dust-free powder that releases active components upon contact with water. The carrier material is sourced from mineral-based inputs, aligning with the material compatibility requirements for green building certifications.

The product incorporates specialized stabilizers designed to generate bubbles with diameters in the range of 0.1–0.5 mm and enhanced wall thickness, aiming to reduce bubble coalescence during mixing and placement. The resulting bubble structure contributes to improved pore size distribution, which is a factor in both thermal performance and mechanical integrity of the cured concrete. Independent laboratory tests have indicated that the powder formulation can achieve compressive strength values 15–20% higher than equivalent liquid foaming agents at the same concrete density level. This performance metric addresses a known trade-off in lightweight concrete production, where density reduction often corresponds to proportional strength loss.

The material is reported to produce no irritating gases, release no harmful substances, and remain stable at room temperature without flammability or explosion hazards. The manufacturer states that the product has met REACH and RoHS compliance requirements.

Application Scope and Usage

The powder foaming agent is applicable to multiple concrete systems, including:

Foamed concrete for roof insulation, underfloor heating, bridge abutment filling, and foundation backfilling (dry densities ranging from 300 to 800 kg/m³). Project data from trial applications indicate material cost savings of 10–20% attributable to reduced transportation weight and minimized on-site waste from leftover diluted liquids.

Aerated concrete blocks and panels, as a replacement for aluminum powder gas-generating agents, offering more uniform pore structures and reaction control during the curing phase.

Precast lightweight partition panels and hollow core slabs, where the agent’s compatibility with automated batching systems supports consistent production quality in factory settings.

Thermal insulation, acoustic, and repair mortars, with compatibility noted for polycarboxylate superplasticizers, retarders, and accelerators.

The product is supplied in bagged form for transport. This packaging format allows for standard container shipping without the hazardous material declarations required for liquid surfactants, simplifying export procedures for international projects. Recommended dosage is 0.05% to 1.0% of cementitious materials by weight, with final adjustment based on target density and trial mix results. Users may apply the dry-mix method or pre-dissolution method according to site conditions. The dry-mix approach is noted to reduce on-site preparation time and minimize batch-to-batch variability associated with manual dilution of liquid agents.
